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.

50a5217637 i965/vec4: split d2x conversion and data gathering from one opcode to two explicit ones
When doing a 64-bit to a smaller data type size conversion, the destination should
be aligned to 64-bits. Because of that, we need to gather the data after the
actual conversion.

Until now, these two operations were done by VEC4_OPCODE_FROM_DOUBLE but
now we split them explicitely in two different instructions:
VEC4_OPCODE_FROM_DOUBLE just do the conversion and
VEC4_OPCODE_PICK_LOW_32BIT will gather the data.

762a6333f2 nir: Rework conversion opcodes
The NIR story on conversion opcodes is a mess.  We've had way too many
of them, naming is inconsistent, and which ones have explicit sizes was
sort-of random.  This commit re-organizes things and makes them all
consistent:

 - All non-bool conversion opcodes now have the explicit size in the
   destination and are named <src_type>2<dst_type><size>.

 - Integer <-> integer conversion opcodes now only come in i2i and u2u
   forms (i2u and u2i have been removed) since the only difference
   between the different integer conversions is whether or not they
   sign-extend when up-converting.

 - Boolean conversion opcodes all have the explicit size on the bool and
   are named <src_type>2<dst_type>.

Making things consistent also allows nir_type_conversion_op to be moved
to nir_opcodes.c and auto-generated using mako.  This will make adding
int8, int16, and float16 versions much easier when the time comes.

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
