[PATCHES] R600/SI: VI fixes

[Marek Olšák]

An updated version is attached. I fixed the shrinking pass for opcodes
that don't have e32 encoding (patch 3). I'm not sure if patch 2 is a
good idea, I'd appreciate some opinion on that.

The MIN3/MAX3 patch is not included here. Still don't know what aspect
of those opcodes should be tested. Also, I can't re-use the current
tests, because the store opcode that the tests use isn't implemented
for VI.
