glcpp: Reject garbage after #else and #endif tokens
Previously we were accepting garbage after #else and #endif tokens when
the previous preprocessor conditional evaluated to false (eg, #if 0).
When the preprocessor hits a false conditional, it switches the lexer
into the SKIP state, in which it ignores non-control tokens. The parser
pops the SKIP state off the stack when it reaches the associated #elif,
#else, or #endif. Unfortunately, that meant that it only left the SKIP
state after the lexing the entire line containing the #token and thus
would accept garbage after the #token.
To fix this we use a mid-rule, which is executed immediately after the
#token is parsed.
NOTE: This is a candidate for the stable branch
