These side-effects seem to make a difference when using llc -march=sparcv9

in the schedule.

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
to do with TargetInstrInfo.

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.)
