#### Compiler changes

1. Deprecate invalid special token sequences inside token strings

   A token string is specified to contain valid D tokens, but the compiler formerly allowed #identifier tokens in them.

       enum s = q{
       #endif x
       }

   This will now issue a deprecation warning. It will become an error in dmd 2.113.
