    PR10025: Test '*' operator vs. identifier while preprocessing
    
    * testsuite/parseok/preprocess-wildcard.stp: New

commit e92f2566001bc913724dbcda25a07e0e8c51418d

    PR10025: Don't read ahead tokens within preprocessor blocks
    
    Since some aspects of the lexer are contextual, like wildcards in
    probepoint identifiers, we need to wait for the right context in the
    preprocessor rather than reading a bunch of tokens at once.
    
    * parse.h (parser): Replace enqueued_pp with a pp_state stack.
    * parse.cxx (parser::scan_pp): Use pp_state to decide if the current
      token should be kept or skipped, and transition states as the various
      %( %? %: %) are encountered.
      (parser::skip_pp): Helper to leap over skipped tokens.
