Patch to use ARRAY_SIZE in more places

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

Simple grep turned up a few more places where we could use the more
legible ARRAY_SIZE in lieu of the explicit verbose sizeof/sizeof
calculation.  Bootstrapped on solaris2.7 (minus ada though.)

Ok to install?

ada:
	* utils.c (init_gigi_decls): Use ARRAY_SIZE in lieu of explicit
	array size calculation.

gcc:
	* c-decl.c (c_decode_option): Use ARRAY_SIZE in lieu of explicit
	array size calculation.
	* gengtype.c (NUM_BASE_FILES, create_file, write_gc_root):
	Likewise.

cp:
	* spew.c (remove_last_token): Use ARRAY_SIZE in lieu of explicit
	array size calculation.
