This builds on the previous draw/softpipe patch.
So llvmpipe does streamout calls after clip/viewport stages,
but we have the pre-clip position stored for later use, so
when we are doing transform feedback, and its the position vertex
grab the vertex from the stored pre clip position.
The perfect fix is too probably add a codegen transform feedback
stage in between shader and clip stages, but this is good enough
for now.

This adds support to draw for the new features of transform feedback.
a) fix count_from_stream_output, using max_index+1 for now but it looks
like it should be valid as its derived from the vertex elements/vbo.
b) fix striding and dst offsets in output buffers - was just wrong before.
c) fix crash if tfb is suspended (so.num_targets == 0)
This also enables the new features on softpipe. It should be possible
to enable them on llvmpipe as well after this commit, but would need
to schedule piglit runs.

Every call to _cl_program::build() was erasing the binaries and logs for
every device associated with the program. This is incorrect because
it is possible to build a program for only a subset of devices and so
any device not being build should not have this information erased.

Override the cross_compiling and ac_tool_prefix variables by reassigning
to them instead of redefining the macros. Redefining them will actually
cause the variable names to be replaced instead of their content.
Furthermore push the definition of CPPFLAGS before running the checks
for the build tools to avoid the host CPPFLAGS from leaking into the
build CPPFLAGS.
While at it drop the redefinition of AC_TRY_COMPILER which hasn't been
used since autoconf 2.50 and make sure that all definitions are properly
popped when done (LDFLAGS, ac_cv_prog_CPP, ac_cv_prog_CXXCPP).

Since we don't call lp_build_sample_common() in the texel fetch path we missed
the layer fixup code. If someone would have tried to do texelFetch with array
textures it would have crashed for sure.
Not really tested (can't run the piglit test being able to use texelFetch with
array samplers for now with llvmpipe).

Previously, if the client program didn't specify a stride when setting
up a vertex attribute, we used _mesa_sizeof_type() to compute the size
of the type, and multiplied it by the number of components.
This didn't work for the 2_10_10_10 formats, since _mesa_sizeof_type()
returns -1 for those types, resulting in all kinds of havoc, since it
was causing the hardware to be programmed with a negative stride
value.
This patch adds a new function _mesa_bytes_per_vertex_attrib(), which
is similar to the existing function _mesa_bytes_per_pixel(), but which
computes the size of a vertex attribute based on the type and the
number of formats. For packed formats (currently only the 2_10_10_10
formats), it verifies that the number of components is correct and
returns the size of the packed format. For unpacked formats, it
returns the size of the type times the number of components.
In addition, this patch adds an assertion so that if we ever forget to
update _mesa_bytes_per_vertex_attrib() when adding a new vertex
format, we'll see the problem quickly rather than having to debug a
subtle conformance test failure.
Fixes GLES3 conformance tests
vertex_type_2_10_10_10_rev_{conversion,divisor,stride_pointer}.test.

The GL 3.1 and ES 3.0 specs say of glGetActiveUniformsiv:
"If an error occurs, nothing will be written to params."
So, make a pass through the indices and check that they're valid before
the pass that actually writes to params. Checking pname happens on the
first iteration of the second loop.
Fixes es3conform's getactiveuniformsiv_for_nonexistent_uniform_indices
test.
NOTE: This is a candidate for the 9.0 branch.

try_rewrite_rhs_to_dst is a quick optimization to avoid generating new
temporaries (and MOVs from those temporaries to the dest) for every
expression tree we visit. By generating better code in simple cases, we
reduce the burden on later optimization passes like register coalescing.
Previously, we compared inst->regs_written() to lhs->vector_elements
to make sure the instruction generating our value wrote the same number
of components as our destination register.
However, this fails in some cases. One example is texturing (which
produces a vec4) into gl_FragData[i]. Technically, gl_FragData[i] is
also a vec4. However, the destination VGRF actually has size 4n (where
n is the size of the array).
split_virtual_grfs() can't split VGRFs that are used by SEND messages
which require contiguous destination registers (like texturing), and
register allocation needs all VGRFs to have sizes between 1 and 4.
Amnesia: The Dark Descent hits this case: a texturing instruction
(4 components) gets rewritten to the gl_FragData output register
(which was 4*3 = 12 components), causing the register allocator to
hit the "we rely on split_virtual_grfs" assertion.
This makes it possible to play Amnesia.

Fetch shaders are usually destroyed at the context destruction by the state
tracker, so we can put them all in a large buffer without wasting memory.
This reduces the number of relocations sent to the kernel a little bit.

This adds seamless sampling for cubemap boundaries if requested.
The corner case averaging is messy but seems like it should be spec
compliant.
The face direction stuff is also a bit messy, I've no idea if that could
or should be simpler, or even if all my directions are fully correct!
v1.1: update comments, drop unneeded seamless calls for nearest, fix
if statement layout.

Before this we only supported user-based constant buffers.
First, we basically plumb pipe_constant_buffer objects through llvmpipe
rather than pipe_resource objects.
Second, update llvmpipe_set_constant_buffer() and try_update_scene_state()
so they understand both resource- and user-based constant buffers.
The problem with user constant buffers is the potential for use-after-free,
as seen in some WebGL tests. The next patch will flip the switch for
resource-based const buffers.

I had tried this in the past, but ran into trouble with applications
that sample from undiscarded pixels in the same subspan. To fix that
issue, only jump to the end for an entire subspan at a time.
Improves GLbenchmark 2.7 (1024x768) performance by 7.9 +/- 1.5% (n=8).
v2: Drop the br variable in the jump instruction -- if I ever do jumps
pre-gen6, it'll be a different code block anyway since we don't have
HALT until gen6.
