d038deaa40 i965/fs: Add remove_extra_rounding_modes optimization
Although from SPIR-V point of view, rounding modes are attached to the
operation/destination, on i965 it is a status, so we don't need to
explicitly set the rounding mode if the one we want is already set.

Taking into account that the default mode is RTE, one possible
optimization would be optimize out the first RTE set for each
block. For in order to work, we would need to take into account block
interrelationships. At this point, it is not worth to complicate the
optimization for such small gain.

v2: Use a single SHADER_OPCODE_RND_MODE opcode taking an immediate
    with the rounding mode (Curro)
v3: Reset optimization for every block. (Jason Ekstrand)

d6cd14f213 i965/fs: Define new shader opcode to set rounding modes
Although it is possible to emit them directly as AND/OR on brw_fs_nir,
having a specific opcode makes it easier to remove duplicate settings
later.

v2: (Curro)
  - Set thread control to 'switch' when using the control register
  - Use a single SHADER_OPCODE_RND_MODE opcode taking an immediate
    with the rounding mode.
  - Avoid magic numbers setting rounding mode field at control register.
v3: (Curro)
  - Remove redundant and add missing whitespace lines.
  - Match printing instruction to IR opcode "rnd_mode"

v4: (Topi Pohjolainen)
  - Fix code style.

deae25ce37 i965: Use separate enums for register vs immediate types
The hardware encodings often mean different things depending on whether
the source is an immediate.

8fa8abef4b i965: Move enums to brw_compiler.h.
These enums live inside struct brw_wm_prog_data, so it makes sense to
keep them in the same header. It also allows to use them without
including brw_eu_defines.h.

6e3265eae5 i965/vec4: split VEC4_OPCODE_FROM_DOUBLE into one opcode per destination's type
This way we can set the destination type as double to all these new opcodes,
avoiding any optimizer's confusion that was happening before.

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
