Remove obsolete TYPE_FLAG_... values

Now that init_type no longer takes a FLAGS argument, there is no user of
the TYPE_FLAGS_... enum values left.  This commit removes them (and all
references to them in comments as well).

This is mostly a no-op, except for a change to the Python type printer,
which attempted to use them before.  (As best as I can tell, this wasn't
really needed anyway, since it was only used to pretty-print type
*instance* flags, which only use the instance flags.)

gdb/ChangeLog:

	* gdbtypes.h (enum type_flag_value): Remove.
	Remove references to TYPE_FLAG_... in comments throughout.
	* gdbtypes.c (recursive_dump_type): Do not print TYPE_FLAG_...
	flags, print the corresponding TYPE_... access macro names.
	Remove references to TYPE_FLAG_... in comments throughout.
	* infcall.c: Remove references to TYPE_FLAG_... in comments.
	* valprint.c: Likewise.
	* gdb-gdb.py (class TypeFlag): No longer consider TYPE_FLAG_...
	values, only TYPE_INSTANCE_FLAG_... values.
	(class TypeFlagsPrinter): Likewise.

gdb/testsuite/ChangeLog:

	* gdb.cp/hang.exp: Remove reference to TYPE_FLAG_STUB in comment.
