James Molloy cefbfa53f9 [SimplifyCFG] Don't create unnecessary PHIs ... In conditional store merging, we were creating PHIs when we didn't need to. If the value to be predicated isn't defined in the block we're predicating, then it doesn't need a PHI at all (because we only deal with triangles and diamonds, any value not in the predicated BB must dominate the predicated BB). This fixes a large code size increase in some benchmarks in a popular embedded benchmark suite. Now with a fix (and fixed tests) for the conformance issue seen in Chromium. llvm-svn: 255767		2015-12-16 14:12:44 +00:00
