3862c570bc For instructions in a delay slot of another instruction, 
we no longer need to find the live-before set of the delayed
branch since that set is now included the live-before/after
set of the instructions in each delay slot.  Just assert that instead.

b047a0d449 All callers of these methods actually wanted them to preserve the flags, 
so get rid of the def/use parameters that were getting passed in.

**** This now changes the semantics of these methods to preserve the flags,
     not clobber them!

b58f52ab45 1. Bug fix: Don't use branch operand reg. as temp. reg. when 
spilling values used by an instruction in the delay slot of the branch
   (which will eventually be moved before the branch).
2. Bug fix:  Delete the delay slot instr, not the branch instr, when
   moving delay slot instr. out!!!!
3. Move code to insert caller-saves moved here from SparcRegInfo:
   it is now machine-independent.

57eb4ab6bc (1) Change the way unused regs. are marked and found to consider regType 
info (since multiple reg types may share the same reg class).
(2) Remove machine-specific regalloc. methods that are no longer needed.
    In particular, arguments and return value from a call do not need
    machine-specific code for allocation.
(3) Rename TargetRegInfo::getRegType variants to avoid unintentional
    overloading when an include file is omitted.
