b5632b5b45 Don't cache the instruction and register info from the TargetMachine, because 
the internals of TargetMachine could change.

No functionality change intended.

e981802d9b R600/SI: fix ELSE pseudo op handling 
Restore the EXEC mask early, otherwise a copy might end up not beeing executed.

Candidate for the mesa stable branch.

e25e490793 R600/SI: cleanup literal handling v3 
Seems to be allot simpler, and also paves the
way for further improvements.

v2: rebased on master, use 0 in BUFFER_LOAD_FORMAT_XYZW,
    use VGPR0 in dummy EXP, avoid compiler warning, break
    after encoding the first literal.
v3: correctly use V_ADD_F32_e64

This is a candidate for the stable branch.

6b7d99d473 R600: New control flow for SI v2 
This patch replaces the control flow handling with a new
pass which structurize the graph before transforming it to
machine instruction. This has a couple of different advantages
and currently fixes 20 piglit tests without a single regression.

It is now a general purpose transformation that could be not
only be used for SI/R6xx, but also for other hardware
implementations that use a form of structurized control flow.

v2: further cleanup, fixes and documentation
