addc55af6c When we have a two-address instruction where the input cannot be clobbered
and is already available, instead of falling back to emitting a load, fall
back to emitting a reg-reg copy.  This generates significantly better code
for some SSE testcases, as SSE has lots of two-address instructions and
none of them are read/modify/write.  As one example, this change does:

        pshufd %XMM5, XMMWORD PTR [%ESP + 84], 255
        xorps %XMM2, %XMM5
        cmpltps %XMM1, %XMM0
-       movaps XMMWORD PTR [%ESP + 52], %XMM0
-       movapd %XMM6, XMMWORD PTR [%ESP + 52]
+       movaps %XMM6, %XMM0
        cmpltps %XMM6, XMMWORD PTR [%ESP + 68]
        movapd XMMWORD PTR [%ESP + 52], %XMM6
        movaps %XMM6, %XMM0
        cmpltps %XMM6, XMMWORD PTR [%ESP + 36]
        cmpltps %XMM3, %XMM0
-       movaps XMMWORD PTR [%ESP + 20], %XMM0
-       movapd %XMM7, XMMWORD PTR [%ESP + 20]
+       movaps %XMM7, %XMM0
        cmpltps %XMM7, XMMWORD PTR [%ESP + 4]
        movapd XMMWORD PTR [%ESP + 20], %XMM7
        cmpltps %XMM4, %XMM0

... which is far better than a store followed by a load!

634c76c08c Fix some nondeterminstic behavior in the mem2reg pass that (in addition to
nondeterminism being bad) could cause some trivial missed optimizations (dead
phi nodes being left around for later passes to clean up).

With this, llvm-gcc4 now bootstraps and correctly compares.  I don't know
why I never tried to do it before... :)
