We'll need to update gallivm for the interface changes in LLVM 3.6, and
the fewer the number of older LLVM versions we support the less hairy that
will be.
As consequence HAVE_AVX define can disappear. (Note HAVE_AVX meant
whether LLVM version supports AVX or not. Runtime support for AVX is
always checked and enforced independently.)
Verified llvmpipe builds and runs with with LLVM 3.3, 3.4, and 3.5.

If the user calls util_blitter_cache_all_shaders() set a flag and assert
that we never try to create any new fragment shaders after that point.
If the assertions fails, it means we missed generating some shader in
util_blitter_cache_all_shaders().

Previously, we generated an extra CMP instruction:
cmp.ge.f0(8) g6<1>D g1<0,4,1>F 0F
cmp.nz.f0(8) null g6<4,4,1>D 0D
(+f0) sel(8) g5<1>F g1.4<0,4,1>F g2<0,4,1>F
The first operand is always a boolean, and we want to predicate the SEL
on that. Rather than producing a boolean value and comparing it against
zero, we can just produce a condition code in the flag register.
Now we generate:
cmp.ge.f0(8) null g1<0,4,1>F 0F
(+f0) sel(8) g5<1>F g1.4<0,4,1>F g2<0,4,1>F
No difference in shader-db.

Using dst_reg(this, ir->type) automatically sets the writemask to the
proper size for the type; src_reg(dst_reg) preserves that. This should
be equivalent, but less code.
Note that src_reg(dst_reg) either uses SWIZZLE_XXXX or SWIZZLE_XYZW, so
the old code did need the manual writemask adjustment, since it
constructed the registers the other way around.

A while back, Matt made the uniform upload functions simply upload
ctx->Const.UniformBooleanTrue for boolean values instead of 0/1, which
removed the need to convert it later. We also set UniformBooleanTrue to
1.0f for drivers which want to treat booleans as 0.0/1.0f.
Nothing ever sets these, so they are dead.

The optimization of avoiding restore (mem2gmem) if there was a clear
falls down a bit if you don't have a fullscreen scissor. We need to
make the decision logic a bit more clever to keep track of *what* was
cleared, so that we can (a) completely skip mem2gmem if entire buffer
was cleared, or (b) skip mem2gmem on a per-tile basis for tiles that
were completely cleared.

The values are hardcoded in the LLVM backend, but the TGSI definitions are
going to be changed with tessellation, e.g. TGSI_PROCESSOR_COMPUTE will be
increased by 2.
We'll use VS for LS and HS, because there's nothing special about them
from the LLVM backend point of view, even though the hardware side is
different. We do the same for ES.
