gdb: remove TYPE_NAME macro

Remove `TYPE_NAME`, changing all the call sites to use `type::name`
directly.  This is quite a big diff, but this was mostly done using sed
and coccinelle.  A few call sites were done by hand.

gdb/ChangeLog:

	* gdbtypes.h (TYPE_NAME): Remove.  Change all cal sites to use
	type::name instead.
