Export to GDB most of lisp.h's remaining object-like macros.

Export to GDB most of lisp.h's remaining object-like macros.

* lisp.h (min, max): Move earlier, because they're used earlier now.
(INTMASK, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK)
(CHAR_TABLE_STANDARD_SLOTS, CHARTAB_SIZE_BITS_0)
(CHARTAB_SIZE_BITS_1, CHARTAB_SIZE_BITS_2, CHARTAB_SIZE_BITS_3)
(DEFAULT_HASH_SIZE, COMPILED_ARGLIST, COMPILED_BYTECODE)
(COMPILED_CONSTANTS, COMPILED_STACK_DEPTH, COMPILED_DOC_STRING)
(COMPILED_INTERACTIVE, CHAR_ALT, CHAR_SUPER, CHAR_HYPER, CHAR_SHIFT)
(CHAR_CTL, CHAR_META, CHAR_MODIFIER_MASK, CHARACTERBITS)
(MANY, UNEVALLED, FLOAT_TO_STRING_BUFSIZE, MAX_ALLOCA):
Now constants, for GDB.  They need not be macros.
(MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM, STRING_BYTES_BOUND):
Now constants, for GDB, as well as macros, for static initializers.
(CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
Move to after the definition of struct Lisp_Char_Table,
since the former now needs that type defined.
(enum CHARTAB_SIZE_BITS, enum CHAR_TABLE_STANDARD_SLOTS)
(enum DEFAULT_HASH_SIZE, enum Lisp_Compiled, enum char_bits)
(enum maxargs, enum FLOAT_TO_STRING_BUFSIZE, enum MAX_ALLOCA):
New enums, for gdb_make_enums_visible.
(GLYPH_MODE_LINE_FACE): Remove; unused.
* alloc.c (STRING_BYTES_MAX): Now a constant, now a macro.
(gdb_make_enums_visible): Add enum CHARTAB_SIZE_BITS, enum
CHAR_TABLE_STANDARD_SLOTS, enum char_bits, enum DEFAULT_HASH_SIZE,
enum FLOAT_TO_STRING_BUFSIZE, enum Lisp_Bits, enum Lisp_Compiled,
enum maxargs, enum MAX_ALLOCA.
(ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): Remove.
(ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Remove;
no longer needed, now that they are done in lisp.h.
