compare. On other targets we end up with a call to memcmp because we don't
want 16 individual byte loads. We should be able to use movups as well, but
we're failing to select the generated icmp.

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
