Fix frame-args.exp failure

[Andreas Schwab <schwab@suse.de>]

This fixes a testsuite failure on powerpc.  print_frame_args didn't
handle arguments that are optimized out (that can happen even in
unoptimized code).

	* stack.c (print_frame_args): Handle LOC_OPTIMIZED_OUT.

testsuite/:
	* gdb.base/frame-args.exp: Handle arguments that are optimized
	out.
