llvm-mc: When handling a .set, make sure to print subsequent references to the
symbol as the symbol name itself, not the expression it was defined to. These have different semantics due to the quirky .set behavior (which absolutizes an expression that would otherwise be treated as a relocation). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79025 91177308-0d34-0410-b5e6-96231b3b80d8
