because we now create constantexprs for the constants instead of failing the
fold.

YACC as bison -y.  In this way, we ensure that bison is being used, but
the Makefiles have macros for using bison itself and for getting bison to
act like it is traditional yacc.

  This allows us to fold expressions like "foo"[2], even if the pointer is only
  a conditional constant.
