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.

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

picking registers like SIL just because ESI was being used.

Just because an alias of a register is available, it doesn't mean that we
can arbitrarily evict the register.
