3d0821a216 intel/vec4: Make implied_mrf_writes() a vec4_instruction method
Same as commit c20dc9b836 (intel/fs: Make implied_mrf_writes() an
fs_inst method.)

4ba445e011 intel: Don't propagate conditional modifiers if a UD source is negated
This fixes a bug uncovered by my NIR integer division by constant
optimization series.

0d5ce25c1c intel/compiler: Add scheduler deps for instructions that implicitly read g0
Otherwise the scheduler can move the writes after the reads.

8f83eea71e i965: Add negative_equals methods
This method is similar to the existing ::equals methods.  Instead of
testing that two src_regs are equal to each other, it tests that one is
the negation of the other.

v2: Simplify various checks based on suggestions from Matt.  Use
src_reg::type instead of fixed_hw_reg.type in a check.  Also suggested
by Matt.

v3: Rebase on 3 years.  Fix some problems with negative_equals with VF
constants.  Add fs_reg::negative_equals.

v4: Replace the existing default case with BRW_REGISTER_TYPE_UB,
BRW_REGISTER_TYPE_B, and BRW_REGISTER_TYPE_NF.  Suggested by Matt.
Expand the FINISHME comment to better explain why it isn't already
finished.

70de61594d i965/fs: Add infrastructure for generating CSEL instructions.
v2 (idr): Don't allow CSEL with a non-float src2.

v3 (idr): Add CSEL to fs_inst::flags_written.  Suggested by Matt.

v4 (idr): Only set BRW_ALIGN_16 on Gen < 10 (suggested by Matt).  Don't
reset the access mode afterwards (suggested by Samuel and Matt).  Add
support for CSEL not modifying the flags to more places (requested by
Matt).

c1fc8fad47 i965/vec4: don't do horizontal stride on some register file types
horiz_offset() shouldn't be doing anything for scalar registers,
because all channels of any SIMD instructions will end up reading or
writing the same component of the register, so shifting the register
offset would be wrong.

a21dc2b500 i965/vec4: split DF instructions and later double its execsize in IVB/BYT
We need to split DF instructions in two on IVB/BYT as it needs an
execsize 8 to process 4 DF values (one GRF in total).

v2:
- Rename helper and make it static inline function (Matt).
- Fix indention and add braces (Matt).

v3:
- Don't edit IR instruction when doubling exec_size (Curro)
- Add comment into the code (Curro).
- Manage ARF registers like the others (Curro)

v4:
- Add get_exec_type() function and use it to calculate the execution
  size.

[ Francisco Jerez: Fix bogus 'type != BAD_FILE' check.  Take
  destination type as execution type where there is no valid source.
  Assert-fail if the deduced execution type is byte.  Clarify comment
  in get_lowered_simd_width().  Move SIMD width workaround outside of
  'if (...inst->size_written > REG_SIZE)' conditional block, since the
  problem should be independent of whether the amount of data written
  by the instruction is greater or lower than a GRF.  Drop redundant
  is_ivb_df definition.  Drop bogus inst->exec_size < 8 check.
  Simplify channel group assertion. ]

700bebb958 i965: Move the back-end compiler to src/intel/compiler
Mostly a dummy git mv with a couple of noticable parts:
 - With the earlier header cleanups, nothing in src/intel depends
files from src/mesa/drivers/dri/i965/
 - Both Autoconf and Android builds are addressed. Thanks to Mauro and
Tapani for the fixups in the latter
 - brw_util.[ch] is not really compiler specific, so it's moved to i965.

v2:
 - move brw_eu_defines.h instead of brw_defines.h
 - remove no-longer applicable includes
 - add missing vulkan/ prefix in the Android build (thanks Tapani)

v3:
 - don't list brw_defines.h in src/intel/Makefile.sources (Jason)
 - rebase on top of the oa patches
