*	Remove use of lookahead from _Pragma handling and from all other	Richard Smith	2019-04-11	1	-0/+22
	internal lexing steps in the preprocessor. It is not safe to use the preprocessor's token lookahead except when operating on the final sequence of tokens that would be produced by phase 4 of translation. Doing so corrupts the token lookahead cache used by the parser. (See added testcase for an example.) Lookahead should instead be viewed as a layer on top of the normal lexer. Added assertions to catch any further incorrect uses of lookahead within lexing actions. llvm-svn: 358230
