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
to do with TargetInstrInfo.

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.)

a979e8a08a ADDI can take several forms, including:
addi r1, r2, 0
  addi r1, <frame index #n>, 0

so we must check for the second parameter being a register for this instruction
to be considered a reg-to-reg copy.
