Evan Cheng 29faaebae9 Add a peephole optimization to optimize pairs of bitcasts. e.g. ... v2 = bitcast v1 ... v3 = bitcast v2 ... = v3 => v2 = bitcast v1 ... = v1 if v1 and v3 are of in the same register class. bitcast between i32 and fp (and others) are often not nops since they are in different register classes. These bitcast instructions are often left because they are in different basic blocks and cannot be eliminated by dag combine. rdar://9104514 llvm-svn: 127668		2011-03-15 05:13:13 +00:00
