0ec92e9d64 Update CodeGen for MRegisterInfo --> TargetInstrInfo changes.

a10fff51d9 Rename SSARegMap -> MachineRegisterInfo in keeping with the idea 
that "machine" classes are used to represent the current state of
the code being compiled.  Given this expanded name, we can start 
moving other stuff into it.  For now, move the UsedPhysRegs and
LiveIn/LoveOuts vectors from MachineFunction into it.

Update all the clients to match.

This also reduces some needless #includes, such as MachineModuleInfo
from MachineFunction.

e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

b2e7316b2d Non-allocatable physregs can be killed and dead, but don't treat them as 
safe for later allocation.  This fixes McCat/18-imp with llc-beta.

9b1a6ebf20 Fix a bunch of llc-beta failures on x86 yesterday. Don't allow selection 
of unallocatable registers, just because an alias is allocatable.  We were
picking registers like SIL just because ESI was being used.

7cc20d418b Fix Regression/CodeGen/Generic/2006-09-02-LocalAllocCrash.ll on X86. 
Just because an alias of a register is available, it doesn't mean that we
can arbitrarily evict the register.

4ff6c1646f Teach the local allocator to know that live-in values (e.g. arguments) are 
live at function entry.  This prevents it from using arg registers for other
purposes before the arguments are used.
