c9b9016d72 Convert many of the virtual TargetInstrInfo methods used as helper 
functions in SparcV9InstrSelection and SparcV9PreSelection into regular
old global functions.  As it happens, none of them really have anything

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.)

a36743c473 Add MRegisterInfo subclass for the SparcV9 target (containing only stub 
functions for now). This automatically turns on the printing of machine
registers using their own real names, instead of goofy things like %mreg(42),
and allows us to migrate code incrementally to the new interface as we see fit.

The register file description it uses is hand-written, so that the register
numbers will match the ones that the SparcV9 target already uses.
Perhaps someday we'll tablegen it.

Divorce state-saving from the doFinalization method; for some reason it's not

PhyRegAlloc::finishSavingState(). Put an abort() in it so that I can be really
really sure that it's getting called.

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.
