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.

info (since multiple reg types may share the same reg class).
(2) Remove machine-specific regalloc. methods that are no longer needed.

machine-specific code for allocation.
(3) Rename TargetRegInfo::getRegType variants to avoid unintentional
overloading when an include file is omitted.

Several fixes to handling of int CC register:
...
(1) An int CC live range must be spilled if there are any interferences,
even if no other "neighbour" in the interf. graph has been allocated
that reg. yet. This is actually true of any class with only one reg!
(2) SparcIntCCRegClass::colorIGNode sets the color even if the LR must
be spilled so that the machine-independent spill code doesn't have to
make the machine-dependent decision of which CC name to use based on
operand type: %xcc or %icc. (These are two halves of the same
register.)
(3) LR->isMarkedForSpill() is no longer the same as LR->hasColor().
These should never have been the same, and this is necessary now for #2 .
(4) All RDCCR and WRCCR instructions are directly generated with the
phony number for %ccr so that EmitAssembly/EmitBinary doesn't have to
deal with this.
