Log:
Fix a typo in dwarf2out.c:resolve_args_picking_1

Under specific circumstances for Ada programs, such as in the testcase
this change adds, the DWARF back-end currently crashes because of
inconsistent internal state. This is due to a typo: a local variable is
called frame_offset_ but resolve_args_picking_1 wrongly modifies
emit-rtl.h's frame_offset instead.

This change fixes this typo.

gcc/
	* dwarf2out.c (resolve_args_picking_1): Replace the frame_offset
	occurence with frame_offset_ ones.

gcc/testsuite/
	* gnat.dg/debug5.adb: New testcase.
