Espically on platforms that do not natively generate 0u and ~0u for
Boolean results, we generate a lot of sequences where a CMP is
followed by an AND with 1. emit_bool_to_cond_code does this, for
example. On ILK, this results in a sequence like:
add(8) g3<1>F g8<8,8,1>F -g4<0,1,0>F
cmp.l.f0(8) g3<1>D g3<8,8,1>F 0F
and.nz.f0(8) null g3<8,8,1>D 1D
(+f0) iff(8) Jump: 6
The AND.nz is obviously redundant. By propagating the cmod, we can
instead generate
add.l.f0(8) null g8<8,8,1>F -g4<0,1,0>F
(+f0) iff(8) Jump: 6
Existing code already handles the propagation from the CMP to the ADD.

v2: Add unit tests suggested by Matt. Remove spurious writes_flag()
check on scan_inst when scan_inst is known to be BRW_OPCODE_CMP (also

v3: Fix some comments and remove some explicit int() casts in fs_reg
constructors in the unit tests. Both suggested by Matt.

This reverts commit 1ee000a0b6.
Failures with the GLES3 conformance suite and Synmark2 OGLHdrBloom revealed
that this commit was in error.
Extensive testing with Piglit prior to patch review and upstreaming did not
reveal this problem because, in the few Piglit tests that test for cube
completeness, NumLayers = 6. This is because all of the existing tests use
TextureStorage to initialize the texture, which sets NumLayers.
A new Piglit test has been sent to the mailing list that reproduces the bug
related to this patch ("texturing: Testing
glGenerateMipmap(GL_TEXTURE_CUBE_MAP) without glTexStorage2D").

Commit 0ac4c27275 made it add a header for the send message when
using SIMD4x2 on Skylake because without this it will end up using
SIMD8D. However the patch missed the case when a sampler is being used
to implement constant loads from a buffer surface in a SIMD4x2 vertex
shader.
This fixes 29 Piglit tests, mostly related to the ARL instruction in
vertex programs.

Commit bb33a31 introduced optimizations that transform cases of MAD
in to simpler forms but it did not take in to account that src[0]
can not be immediate and did not report progress. Patch switches
src[0] and src[1] if src[0] is immediate and adds progress
reporting. If both sources are immediates, this is taken care of by
the same opt_algebraic pass on later run.

Previously PTHREAD_MUTEX_RECURSIVE_NP had been used on linux for
compatibility with old glibc. Since mesa defines __GNU_SOURCE__
on linux PTHREAD_MUTEX_RECURSIVE is also available since at least
1998. So we can unconditionally use the portable version
PTHREAD_MUTEX_RECURSIVE.

I have to use the BFE instrinsics, because BFE is one of the most complex
instructions that can't be matched easily. BFE has 3 conditional branches
and one of them is quite big.
In the isel DAG, lowered BFE has 27 nodes (including leafs).
