a71776e676 As it happens, none of these TargetInstrInfo methods which are only 
used in the SparcV9 backend really have anything to do with
TargetInstrInfo, so we're converting them into regular old global
functions and moving their declarations to SparcV9InstrSelectionSupport.h.
(They're mostly used as helper functions for SparcV9InstrSelection.)

b78f8498f0 TargetCacheInfo has been removed; its only uses were to propagate a constant 
(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's
dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in
the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.

c6a7c83333 Change all machine basic block modifier functions in MRegisterInfo to 
return the number of instructions added to/removed from the basic block
passed as their first argument.

Note: This is only needed because we use a std::vector instead of an
ilist to keep MachineBasicBlock instructions. Inserting an instruction
to a MachineBasicBlock invalidates all iterators to the basic
block. The return value can be used to update an index to the machine
basic block instruction vector and circumvent the iterator elimination
problem but this is really not needed if we move to a better
representation.
