[PATCH 1/2] minor cleanups in is_dynamic_type

[Tom Tromey <tromey@redhat.com>]

I noticed that gdbtypes.c:is_dynamic_type has some unneeded "break"s.
This patch cleans up the function a bit, removing those and removing
the switch's default case so that the end of the function is a bit
clearer.

	* gdbtypes.c (is_dynamic_type): Remove unneeded "break"s.
