dbd00bf51a R600/SI: Move continue after checking s_mov_b32. 
There's nothing else to bother trying to shrink these.

6035518e3b Have MachineFunction cache a pointer to the subtarget to make lookups 
shorter/easier and have the DAG use that to do the same lookup. This
can be used in the future for TargetMachine based caching lookups from
the MachineFunction easily.

Update the MIPS subtarget switching machinery to update this pointer
at the same time it runs.

17c8fefc9f R600/SI: Do abs/neg folding with ComplexPatterns 
Abs/neg folding has moved out of foldOperands and into the instruction
selection phase using complex patterns.  As a consequence of this
change, we now prefer to select the 64-bit encoding for most
instructions and the modifier operands have been dropped from
integer VOP3 instructions.

635fb9fb59 R600/SI: Fold immediates when shrinking instructions 
This will prevent us from using extra MOV instructions once we prefer
selecting 64-bit instructions.

e5fc4208eb R600/SI: Fix incorrect commute operation in shrink instructions pass 
We were commuting the instruction by still shrinking it using the
original opcode.

NOTE: This is a candidate for the 3.5 branch.

9787e8c76b R600/SI: Add instruction shrinking pass 
This pass converts 64-bit instructions to 32-bit when possible.
