6e7b76ce94 Do not sort by the address of LLVM ConstantInt* objects. This produces
nondeterministic results that depend on where these objects land in memory.
Instead, sort by the value of the constant, which is stable.

Before this patch, the -simplifycfg pass run from two different compilers
could cause different code to be generated, though it was semantically the
same:

We need to stomp all of this stuff out.

5b4da6dd16 Do not loop over uses as we delete them. This causes iterators to be
invalidated out from under us.  This bug goes back to revision 1.1: scary.

modifications for 1 LLVM BB --> many MBBs).

"[ Base + Offset ] = SrcReg").

the branch fallthrough trick, for the time being.

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.
