When we have native integers, these have full precision. Whether they're
low/medium/high isn't piped through the TGSI yet, but eventually those
might have differing precisions. For now they're just 32-bit ints.
Fixes the following dEQP tests:
dEQP-GLES3.functional.state_query.shader.precision_vertex_highp_int
dEQP-GLES3.functional.state_query.shader.precision_fragment_highp_int
which expected highp ints to have full 32-bit precision, not the default
23-bit float precision.

We make sure that that image depth matches the level's depth before
copying it into place. However we should only be minifying the first
level's depth for 3d textures - array textures have the same depth for
all levels.
This fixes tests such as
dEQP-GLES3.functional.texture.specification.texsubimage3d_depth.* and I
suspect account for a number of other odd situations I've run into where
level > 0 of array textures was messed up.

Fixes:
dEQP-GLES3.functional.negative_api.state.get_framebuffer_attachment_parameteriv
Apparently, GL_FRAMEBUFFER_ATTACHMENT_OBJECT_NAME is not allowed when
GL_FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE is GL_FRAMEBUFFER_DEFAULT, and
is expected to result in a GL_INVALID_ENUM error.
No GL specification actually defines what GL_FRAMEBUFFER_DEFAULT means.
It probably means the window system FBO. It also doesn't mention the
behavior of any queries for that type. Various ARB folks seem fairly
confused about it too. For now, just do something vaguely like what
dEQP expects.
I think we probably need to check the visual bits against 0 for the
attachment, but we haven't been doing that thusfar, and given how
confusingly this is specified, I can't imagine anyone relying on it.
v2: Improve comments, move error condition above the
_mesa_get_fb0_attachment call, add forgotten "return"
(all suggested/caught by Jordan Justen).

According to the OpenGL ES 3.2 spec's description of GenerateMipmap:
"An INVALID_OPERATION error is generated if the levelbase array was not
specified with an unsized internal format from table 8.3 or a sized
internal format that is both color-renderable and texture-filterable
according to table 8.10."
Similar text exists in the ES 3.0 specification as well.
Our existing rules are pretty close, but miss a few things. The
OpenGL specification actually doesn't have any text about internal
format checking - our existing code comes from a Khronos bug report.
The ES 3.x spec provides a clearer description.
Fixes dEQP-GLES3.functional.negative_api.texture.generatemipmap and
dEQP-GLES2.functional.negative_api.texture.generatemipmap_zero_level

OpenGL ES 3.x contains a table of sized internal formats and their
required properties. In particular, each format is marked as
"Color Renderable" or "Texture Filterable".
This patch introduces two functions that can be used to query the
information from that table.

Wide points and lines are not supposed to be clipped by the viewport.
Rather, they should be rendered, and any fragments outside of the
viewport should be discarded.
The traditional use case for this behavior is rendering moving wide
point particles. When the center of the point approaches the viewport
edge, clipping would make it pop out of view early.

We're about to start allowing wide points/lines whose vertices are
outside the viewport past the clipper. This scissoring hack ensures
that any fragments generated are still restricted to the viewport.
It is not necessary on Gen8+ as those platforms already discard
fragments which are outside the viewport.

Thanks to James Legg for finding this!
From the ARB_tessellation_shader spec:
"The number of isolines generated is derived from the first outer
tessellation level; the number of segments in each isoline is
derived from the second outer tessellation level."
According to the PRM, "TF.LineDensity determines # lines" while
"TF.LineDetail determines # segments". Line Density is stored at
DWord 6, while Line Detail is at DWord 7. So, they're not reversed
like they are for triangles and quads.
Fixes Piglit's spec/arb_tessellation_shader/execution/isoline,
and about 24 dEQP isoline tests (with GL_EXT_tessellation_shader
hacked on - it's not normally enabled).

The bitcasting which is possible with shader images (and texture views?)
requires that when the user specifies a sized internal format for a
texture, we really allocate that format. To this end:
(1) find_exact_format should ignore sized internal formats and
(2) some of the entries in the mapping table corresponding to sized
internal formats are reordered to use an RGBA format instead of
a BGRA one.
This fixes arb_shader_image_load_store-bitcast in the (work in progress)
ARB_shader_image_load_store implementation for radeonsi.
v2: don't change the mapping of GL_RGB10: the change caused a regression

Some opcodes need explicit bitsizes, and sometimes we need to use the
double version when constant folding.
v2: fix output type for u2f (Iago)
v3: do not change vecN opcodes to be float. The next commit will add
infrastructure to enable 64-bit integer constant folding so this is isn't
really necessary. Also, that created problems with source modifiers in
some cases (Iago)
v4 (Jason):
- do not change bcsel to work in terms of floats
- leave ldexp generic
Squashed changes to handle different bit sizes when constant
folding since otherwise we would break the build.
v2:
- Use the bit-size information from the opcode information if defined (Iago)
- Use helpers to get type size and base type of nir_alu_type enum (Sam)
- Do not fallback to sized types to guess bit-size information. (Jason)
Squashed changes in i965 and gallium/nir drivers to support sized types.
These functions should only see sized types, but we can't make that change
until we make sure that nir uses the sized versions in all the relevant places.
A later commit will address this.

This code in brw_set_dest adjusts the execution size of any instruction
with a dst.width < 8. However, we don't want to do this with instructions
operating on doubles, since these will have a width of 4, but still
need an execution size of 8 (for SIMD8). Unfortunately, we can't just check
the size of the operands involved to detect if we are doing an operation on
doubles, because we can have instructions that do operations on double
operands interpreted as UD, operating on any of its 2 32-bit components.
Previous commits have made it so we never emit instructions with a horizontal
width of 4 that don't have the correct execution size set for gen6+, so
we can skip it in this case, avoiding the conflicts with fp64 requirements.
Expanding the same fix to other hardware generations requires many more
changes but since we are not targetting fp64 support on them
wer don't really care for now.

Previously, we gave our internal clear/blit shaders actual GL handles
and stored them in the shader/program hash table. We used ordinary
GL API entrypoints to work with them.
We thought this shouldn't be a problem because GL doesn't allow
applications to invent their own names for shaders or programs.
GL allocates all names via glCreateShader and glCreateProgram.
However, having them in the hash table is a bit risky: if a broken
application guesses the name of our shaders or programs, it could
alter them, potentially screwing up future meta operations.
Also, test cases can observe the programs in the hash table. Running
a single dEQP process that executes the following test list:
dEQP-GLES3.functional.negative_api.buffer.clear
dEQP-GLES3.functional.negative_api.shader.compile_shader
dEQP-GLES3.functional.negative_api.shader.delete_shader
would result in the last two tests breaking. The compile_shader test
calls glCompileShader(9) straight away, and since it hasn't even created
any shaders or programs, it expects to get a GL_INVALID_VALUE error
because there's no such name. However, because the clear test ran
first, it created Meta programs, so an object named "9" did exist.
This patch reworks Meta to work with gl_shader and gl_shader_program
pointers directly. These internal programs have bogus names, and are
never stored in the hash tables, so they're invisible to applications.

This is cleaner than using glBindAttribLocation().
Not all drivers support the extension, but I don't think those drivers
use GLSL in the first place. Apparently some Meta shaders already use
GL_ARB_explicit_attrib_location, so I think it should be okay.
Honestly, I'm not sure how the old code worked anyway - we bound the
attribute location for "texcoords", while all the shaders capitalized
or spelled it differently.
