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

There may not be a previous block. In this case, there's no real work

This will now never occur. The empty if-else part would have already
been removed leaving an empty if-endif part.

'git diff -w' is a bit more illustrative. A couple declarations were
moved, the continue was removed, and the code was reindented. This will
simplify future changes.

The backend_shader class really is a representation of a shader. The fact
that it inherits from ir_visitor is somewhat immaterial.

I used these in the SEL peephole, but they require extra tracking and
fix ups. The SEL peephole can pretty easily find the blocks it needs
without these.

Now that nothing invalidates the CFG, we can calculate_cfg() immediately

This pass deletes an IF/ELSE/ENDIF or IF/ENDIF sequence, or the ELSE in
an ELSE/ENDIF sequence.
In the typical case (where IF and ENDIF) aren't the only instructions in
their basic blocks, we can simply remove the instructions (implicitly
deleting the block containing only the ELSE), and attempt to merge
blocks B0 and B2 together.
B0: ...
(+f0) if(8)
B1: else(8)
B2: endif(8)
...
If the IF or ENDIF instructions are the only instructions in their
respective basic blocks (which are deleted by the removal of the
instructions), we'll want to instead merge the next blocks.
Both B0 and B2 are possibly removed by the removal of if & endif.
Same situation for if/endif. E.g., in the following example we'd remove
blocks B1 and B2, and then attempt to combine B0 and B3.
B0: ...
B1: (+f0) if(8)
B2: endif(8)
B3: ...

Use this as an opportunity to rename 'block_num' to 'num'. block->num is
clear, and block->block_num has always been redundant.

Previously we made the basic block following an ENDIF instruction a
successor of the basic blocks ending with IF and ELSE. The PRM says that
IF and ELSE instructions jump *to* the ENDIF, rather than over it.
This should be immaterial to dataflow analysis, except for if, break,
endif sequences:
START B1 <-B0 <-B9
0x00000100: cmp.g.f0(8) null g15<8,8,1>F g4<0,1,0>F
0x00000110: (+f0) if(8) 0 0 null 0x00000000UD
END B1 ->B2 ->B4
START B2 <-B1
break
0x00000120: break(8) 0 0 null 0D
END B2 ->B10
START B3
0x00000130: endif(8) 2 null 0x00000002UD
END B3 ->B4
The ENDIF block would have no parents, so dataflow analysis would
generate incorrect results, preventing copy propagation from eliminating
some instructions.
This patch changes the CFG to make ENDIF start rather than end basic
blocks, so that it can be the jump target of the IF and ELSE
instructions.
It helps three programs (including two fs8/fs16 pairs).
total instructions in shared programs: 1561126 -> 1561060 (-0.00%)
instructions in affected programs: 837 -> 771 (-7.89%)
More importantly, it allows copy propagation to handle more cases.
Disabling the register_coalesce() pass before this patch hurts 58
programs, while afterward it only hurts 11 programs.
