Omit duplicate definitions no longer needed with gcc -g3.

* lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
(VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
Define only as macros.  There's no longer any need to also define
these symbols as enums or as constants, since we now assume
gcc -g3 when debugging.
