gdb: change bcache::insert `added` parameter to bool

It is currently an int, but it is used as a bool.

gdb/ChangeLog:

	* bcache.h (struct bcache) <insert>: Change type of `added` to
	pointer to bool.
	* bcache.c (bcache::insert): Likewise.
	* gdbtypes.c (check_types_worklist): Adjust.
	* psymtab.c (add_psymbol_to_bcache): Adjust.
