Patch to fix PR337. Make sure to mark all aliased physical registers as used when we see a read of a register. This is important in cases like: AL = ... AH = ... = AX The read of AX must make both the AL and AH defs live until the use. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13444 91177308-0d34-0410-b5e6-96231b3b80d8
