MC/AsmParser: Avoid unnecessary use of SourceMgr::FindBufferForLoc() - Each macro instantiation introduces a new buffer, and FindBufferForLoc() is linear, so previously macro instantiation could be N^2 for some pathological inputs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169073 91177308-0d34-0410-b5e6-96231b3b80d8
