radeonsi: do EarlyCSEMemSSA LLVM pass
so that LLVM IR looks like CSE has been run on it. It's also recommended
by the instruction combining pass.
This also fixes:
- GL45-CTS.arrays_of_arrays_gl.InteractionFunctionCalls2 (crash)
- piglit/spec/arb_shader_ballot/execution/fs-readFirstInvocation-uint-loop (fail)
The code size decrease is positive, the register usage isn't. There is
a decrease in VGPR spilling for Tomb Raider, but increase in DiRT Showdown
and GRID Autosport.
EarlyCSEMemSSA has a -0.01% change in code size compared EarlyCSE.
