"inlineasmstart/end" strings so that the contents of the directive are separate from the comment character. This lets elf targets get #APP/#NOAPP for free even if they don't use "#" as the comment character. This also allows hoisting the darwin stuff up to the shared TAI class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78737 91177308-0d34-0410-b5e6-96231b3b80d8
