d496780fb2 intel/eu/validate: Look up types on demand in execution_type()
We are looking up the execution type prior to checking how many sources
we have.  This leads to looking for a type for src1 on MOV instructions
which is bogus.  On BDW+, the src1 register type overlaps with the
64-bit immediate and causes us problems.

dff75c7175 i965: Drop unnecessary conditional
Clang doesn't realize that 0 and 1 are the only possibilities, a thinks
lots of variables might be uninitialized.

9fb8323328 i965: Rename brw_inst's functions that access the register type
Put hw_ in the name so that it's clear these are the hardware encodings.

890f863da0 i965: Reverse file/type arguments to register type functions
I think of the initial arguments as "state" and the last as the actual
subject.

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.

UB and B type encodings are the same as UV and VF. Noticed when writing
the following patch.

fd349d29e4 i965: Handle IVB DF differences in the validator.
On IVB/BYT, region parameters and execution size for DF are in terms of
32-bit elements, so they are doubled. For evaluating the validity of an
instruction, we halve them.

v2 (Sam):
- Add comments.

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
