[PATCH 10/14] make dwarf_expr_frame_base_1 public

[Tom Tromey <tromey@redhat.com>]

This exports dwarf_expr_frame_base_1 so that other code can use it.

2014-05-16  Tom Tromey  <tromey@redhat.com>

	* dwarf2loc.h (dwarf_expr_frame_base_1): Declare.
	* dwarf2loc.c (dwarf_expr_frame_base_1): Now public.
