correct: empirically, "regType" is wrong for a number of registers. Thus, one can only rely on the "regClass" to figure out what kind of register one is dealing with. This change switches to using only "regClass" and adds a few extra DEBUG() print statements and a few clean-ups in comments and code, mostly minor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7103 91177308-0d34-0410-b5e6-96231b3b80d8
