MacroArgs - An instance of this class captures information about the formal arguments specified to a function-like macro invocation.

ArgNeedsPreexpansion - If we can prove that the argument won't be affected by pre-expansion, return false. Otherwise, conservatively return true.

isVarargsElidedUse - Return true if this is a C99 style varargs macro invocation and there was no argument specified for the "..." argument. If the argument was specified (even empty) or this isn't a C99 style varargs function, or if in strict mode and the C99 varargs macro had only a ... argument, this returns false.

StringifyArgument - Implement C99 6.10.3.2p2, converting a sequence of tokens into the literal string token that should be produced by the C # preprocessor operator. If Charify is true, then it should be turned into a character literal for the Microsoft charize (#@) extension.
