PR preprocessor/34692
	* macro.c (collect_args): Add pragma_buff argument.  Push
	CPP_PRAGMA ... CPP_PRAGMA_EOL tokens to *pragma_buff, rather
	than into arguments.  Reset prevent_expansion and parsing_args
	state at CPP_PRAGMA_EOL/CPP_EOF.
	(funlike_invocation_p): Add pragma_buff argument, pass it through
	to collect_args.
	(enter_macro_context): Add result argument.  Adjust
	funlike_invocation_p caller.  Emit all deferred pragma tokens
	gathered during collect_args before the expansion, add a padding
	token.  Return 2 instead of 1 if any pragma tokens were prepended.
	(cpp_get_token): If enter_macro_context returns 2, don't return
	a padding token, instead cycle to grab CPP_PRAGMA token.
	* directives.c (_cpp_handle_directive): If was_parsing_args
	in deferred pragma, leave parsing_args and prevent_expansion as is.
