gas frag_var

gas frag_var

Many frag_var calls have unnecessary casts on arguments, no doubt from
the days when binutils was written for K&R C.  (ie. functions were not
prototyped so you needed to cast anything that didn't match the
expected type after default promotions, as you still do for args
matching a function ellipsis.)  Remove those casts.

	* config/tc-alpha.c (s_alpha_comm): Use offset_T for cur_size
	to avoid need for casts.  Remove casts from frag_var args.

	frag_var args.
