Craig Topper fd38cbebda Remove 'virtual' keyword from methods markedwith 'override' keyword.

Eric Christopher fc6de428c8 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.

Eric Christopher d913448b38 Remove the TargetMachine forwards for TargetSubtargetInfo based 
information and update all callers. No functional change.

Tom Stellard b4a313a76f 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.

Tom Stellard 6407e1e632 R600/SI: Fold immediates when shrinking instructions 
This will prevent us from using extra MOV instructions once we prefer
selecting 64-bit instructions.

Tom Stellard 86d12ebdbd 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.

Tom Stellard 1aaad6970c R600/SI: Add instruction shrinking pass 
This pass converts 64-bit instructions to 32-bit when possible.
