In commit 055093e (meta: remove call to _meta_in_progress(), fix
multisample enable/disable), we created a meta_set_enable() function
that could be used by meta ops to enable and disable GL_MULTISAMPLE
even when the GLES API was in use (the GLES API doesn't support
GL_MULTISAMPLE; it behaves as if it is always enabled). This created
some unfortunate code duplication between meta_set_enable() and the
existing _mesa_set_enable() function.
This patch eliminates the duplication by creating a
_mesa_set_multisample() function, which is used by both meta ops and
_mesa_set_enable() to enable/disable GL_MULTISAMPLE.

ARB fragment programs use texture unit numbers directly, unlike GLSL
which has an extra indirection. If a fragment program only uses one
texture assigned to GL_TEXTURE1, SamplersUsed will only contain a single
bit, which would make us only upload a single surface/sampler state
entry. However, it needs to be the second entry.
Using _mesa_fls() instead of _mesa_bitcount() solves this. For ARB
programs, this makes num_samplers the ID of the highest texture unit
used. Since GLSL uses consecutive integers assigned by the linker,
_mesa_fls() should give the same result as _mesa_bitcount()..
Fixes a regression since 85e8e9e000732908b259a7e2cbc1724a1be2d447,
which caused GPU hangs in ETQW (and probably others), as well as

Previously, we aligned all stencil blit operations to multiples of the
size of a tile, since stencil buffers use W-tiling, and blorp has to
approximate this by configuring the 3D pipeline for Y-tiling and
swizzling coordinates.
However, this was unnecessarily conservative; it turns out that the
differences between W-tiling and Y-tiling are confined to 32-byte
sub-tiles within the 4k tiling pattern; the layout of these 32-byte
sub-tiles within the larger 4k tile is the same (8 sub-tiles across by
16 sub-tiles down, in column-major order). Therefore we only need to
align stencil blit operations to multiples of the sub-tile size.
Note: although the performance improvement of this change is probably
quite small, the fact that W-tiling and Y-tiling formats only differ
within 32-byte sub-tiles will be essential in a future patch to ensure
that stencil blits work correctly between parts of the miptree other
than level/layer 0. Making this change provides handy documentation
(and validation) of this fact.

When blitting to a stencil buffer, we need to align the rectangle we
send down the rendering pipeline, to account for the fact that the
stencil buffer uses a W-tiled layout, but we are configuring its
surface state as Y-tiled.
Previously, when the stencil buffer was multisampled, we assumed that
we could reduce the amount of alignment that was necessary, since each
pixel occupies a block of 2x2 or 4x2 samples in the stencil buffer.
That would have been correct if the coordinates we were adjusting were
measured in pixels. However, the conversion from pixel coordinates to
coordinates within the interleaved buffer has already been done;
therefore the full alignment restriction applies.
Note: the reason this mistake wasn't previously uncovered by piglit
tests is because it is being masked by another mistake: the blorp
engine is using overly conservative alignment restrictions when doing
stencil blits. The overly conservative alignment restrictions will be
removed in the patch that follows. Doing this fix now will prevent
the subsequent patch from introducing regressions.

When the blorp engine is performing a blit from one stencil buffer to
another, it sets up the surface state for these buffers as Y-tiled, so
it needs to be able to force intel_region_get_tile_masks() to return
the appropriate masks for a Y-tiled region.

Previously, when performing a blit using the blorp engine, we failed
to account for the level and layer of the source and destination. As
a result, all blits would occur between miplevel 0 and layer 0 of the
corresponding textures, regardless of which level/layer was bound to
the framebuffer.
This patch passes the correct level and layer through
brw_blorp_miptrees() into the brw_blorp_blit_params data structure.
Further patches in the series will adapt
gen{6,7}_blorp_emit_surface_state to make use of these parameters.

Currently, gen{6,7}_blorp_emit_surface_state assumes that the src and
dst surfaces are mapped to miplevel 0 and layer 0 (thus no surface
offset is required). This is a bug, since the user might try to blit
to and from levels/layers other than 0.
To fix this bug, it will not be sufficient to have
gen6_{6,7}_blorp_emit_surface_state look up the surface offset at the
time they set up the surface state, since these offsets will need to
be tweaked when blitting stencil buffers (due to the fact that stencil
buffer blits have to swizzle between W and Y tiling formats).
So, to pave the way for the bug fix, this patch causes the x and y
offsets to be computed during blit setup and stored in
brw_blorp_mip_info.
As a result of this change, brw_blorp_mip_info doesn't need to store
the level and layer anymore.
For consistency, this patch makes a similar change to the handling of
depth buffers when doing HiZ operations.

Previously, gen{6,7}_blorp_emit_surface_state would look up the width
and height of the surface at the time they set up the surface state,
and then tweak it if necessary (it's necessary when a W-tiled surface
is being mapped as Y-tiled). With this patch, we look up the width
and height when setting up the blit, and store them in
brw_blorp_mip_info. This allows us to do the necessary tweak in the
brw_blorp_blit_params constructor (where it makes more sense). It
also reduces the need to keep track of level and layer in
brw_blorp_mip_info, so that a future patch can eliminate them
entirely.

Since Gen6+ stencil buffers use W-tiling (a tiling arrangement which
drm and the kernel are not aware of) we need to round up the width and
height of a stencil buffer to multiples of the W-tile size (64x64)
before allocating a stencil buffer. Previously, we rounded up the
size of the base miplevel, and then computed the miptree layout based
on the rounded up size. This was incorrect, because it meant that the
total size of the miptree would not be properly W-tile aligned, and
therefore we would not always allocate enough pages.
(Note: even though the GL API doesn't allow creation of mipmapped
stencil textures, it does allow mipmapping of a combined depth/stencil
texture, and on Gen6+, a combined depth/stencil texture is internally
implemented as a pair of separate depth and stencil buffers.)
For example, on Sandy Bridge, when allocating a mipmapped stencil
texture of size 128x128, we would first round up to the nearest
multiple of 64x64 (causing no change to the size), and then compute
the miptree layout (whose size worked out to 128x196). Then we would
request an allocation of 128*196 bytes (6.125 pages), causing 7 pages
to be allocated to the texture. However, the texture needs 8 pages,
since each W-tile occupies a page, and it takes 2 W-tiles to cover a
width of 128 and 4 W-tiles to cover a height of 196.
This patch changes the order of operations so that the miptree layout
is computed first and then the total size of the miptree is rounded up
to be W-tile aligned.

Haswell moved the "Cut Index Enable" bit from the INDEX_BUFFER packet to
a new 3DSTATE_VF packet, so we need to emit that. Also, it requires us
to specify the cut index rather than assuming it's 0xffffffff.
This adds a new Haswell-specific tracked state atom to gen7_atoms.
Normally, we would create a new generation-specific atom list, but since
there's only one difference over Ivybridge so far, I chose to simply
make it return without doing any work on non-Haswell systems.

According to Eric, this shouldn't matter since we don't do precompiles
using the old backend. In other words, brw->fragment_program (the
currently active program) should equal c->fp (the program currently
being compiled).
However, it's just not a good idea to access brw->fragment_program
directly in compiler code. It's totally illegal in the new backend, so
let's just not do it here either.

Prior to commit 2f1869822, emit_fb_writes() looped from 0 to 3, writing
all four components of a vec4 color output. However, that broke for
smaller output types (float, vec2, or vec3). To fix that, I introduced
a new variable (output_components[]) containing the size of the output
type for each render target.
Unfortunately, I forgot to actually initialize it in the constructor,
which meant that unless a shader wrote to gl_FragColor, or the specific
output for each render target, output_components would contain a garbage
value, and we'd loop for a completely non-deterministic amount of time.
Not actually emitting any color writes seems like the right approach.
We may still need to emit a render target write (to terminate the
thread), but don't have to put in any sensible values (the shader didn't
write anything, after all).
