Fix PR5024. LiveVariables physical register defs should *commit* only after all
of the defs are processed. Also fix a implicit_def propagation bug: a implicit_def of a physical register should be applied to uses of the sub-registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82616 91177308-0d34-0410-b5e6-96231b3b80d8
