C++ PATCH for c++/67339 (ICE with alias to PMF)

[Jason Merrill]

We can't assume that a RECORD_TYPE has TYPE_LANG_SPECIFIC anymore.

Tested x86_64-pc-linux-gnu, applying to trunk and 5.

    	PR c++/67339
    	* parser.c (cp_parser_elaborated_type_specifier): Use CLASS_TYPE_P
    	rather than check for RECORD_TYPE.
