This commit extends the machine instruction lexer and implements support for the quoted global value tokens. With this change the syntax for the global value identifier tokens becomes identical to the syntax for the global identifier tokens from the LLVM's assembly language. Reviewers: Duncan P. N. Exon Smith git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@242702 91177308-0d34-0410-b5e6-96231b3b80d8
