i965: Don't copy propagate abs into Broadwell logic instructions.
It's not clear what abs on logical instructions means on Broadwell, and
it doesn't appear to do anything sensible.
Fixes 270 Piglit tests (the bitand/bitor/bitxor tests with abs).

i965/fs: Use WE_all for gl_SampleID header register munging.
This code should execute without regard to the currently executing
channels. Asking for gl_SampleID inside control flow might break in
strange ways. It appears to break even at the top of the program in
SIMD16 mode occasionally as well.

i965/fs: Set force_uncompressed and force_sechalf on samplepos setup.
gen8_fs_generator uses these to decide whether to set the execution size
to 8 or 16, so we incorrectly made both of these MOVs the full width in
SIMD16 shaders. (It happened to work out on Gen4-7.)
Setting them should also help inform optimization passes what's really
going on, which could help avoid bugs.

i965: Set execution size to 8 for instructions with force_sechalf set.
Both inst->force_uncompressed and inst->force_sechalf mean that the
generated instruction should be uncompressed and have an execution size
of 8. We don't require the visitor to set both flags - setting
inst->force_sechalf by itself is supposed to be enough.
On Gen4-7, guess_execution_size() demoted instructions to 8-wide based
on the default compression state. On Gen8+, we instead set a default
execution size, which worked great...except that we forgot to check
inst->force_sechalf when deciding whether to use 8 or 16.

radeonsi: properly implement texture opcodes that take an offset
Instead of using intr_name in lp_build_tgsi_action, this selects the names
with a switch statement in the emit function. This allows emitting
llvm.SI.sample for instructions without offsets and llvm.SI.image.sample.*.o
otherwise.
This depends on my LLVM changes.
When LLVM 3.5 is released, I'll switch all texture instructions to the new
intrinsics.
