Cameron Zwarich	09c312acad	When scalar replacement returns a vector type, only accept it if the vector ... type's bitwidth matches the (allocated) size of the alloca. This severely pessimizes vector scalar replacement when the only vector type being used is something like <3 x float> on x86 or ARM whose allocated size matches a <4 x float>. I hope to fix some of the flawed assumptions about allocated size throughout scalar replacement and reenable this in most cases. llvm-svn: 133338	2011-06-18 06:17:51 +00:00
