out the remainder of the calls that we should lower in some way and
move the tests to the new correct directory. Fix up tests that are now
optimized more than they were before by -instcombine.

move an optimization for memcmp out of simplifylibcalls and into 2009-12-24T00:37:38ZChris Lattnersabre@nondot.org2009-12-24T00:37:38Zurn:sha1:8047d9a6be9c6261c4d3f286786be856d619ed0f
SDISel. This optimization was causing simplifylibcalls to
introduce type-unsafe nastiness. This is the first step, I'll be
expanding the memcmp optimizations shortly, covering things that
we really really wouldn't want simplifylibcalls to do.

miscompile (i386.o miscompares) but it happens both with and without
this patch.
