RegisterCoalescer: Fix valuesIdentical() in some subrange merge cases. I got confused and assumed SrcIdx/DstIdx of the CoalescerPair is a subregister index in SrcReg/DstReg, but they are actually subregister indices of the coalesced register that get you back to SrcReg/DstReg when applied. Fixed the bug, improved comments and simplified code accordingly. Testcase by Tom Stellard! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225415 91177308-0d34-0410-b5e6-96231b3b80d8
