8464a0bf00 Add a argument to storeRegToStackSlot and storeRegToAddr to specify whether 
the stored register is killed.

8ee9065162 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.

d269774664 Non-allocatable physregs can be killed and dead, but don't treat them as

16e4937a31 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.

ff7657a869 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.

48823987ff 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.

1b8f37597d Fix a recent regression in Applications/sgefa that Alkis pointed out to me. 
The vector may actually be empty if the register that we are marking as
recently used is not actually allocatable.  This happens for physical registers
that are not allocatable, like the ST(x) registers on X86.
