Remove get_frame_cfa from dwarf_expr_context

Browse Source 
Following the idea of merging the evaluators, the get_frame_cfa method
can be moved from dwarf_expr_executor and dwarf_evaluate_loc_desc
classes to their base class dwarf_expr_context. Once this is done,
it becomes apparent that the method is only called once and it can be
inlined.

It is also necessary to check if the frame context information was
provided before the DW_OP_call_frame_cfa operation is executed.

gdb/ChangeLog:

	* dwarf2/expr.c (dwarf_expr_context::get_frame_cfa): Remove
	method.
	(dwarf_expr_context::execute_stack_op): Call frame context info
	check for DW_OP_call_frame_cfa. Remove use of get_frame_cfa.
	* dwarf2/expr.h (dwarf_expr_context::get_frame_cfa): Remove
	method.
	* dwarf2/frame.c (dwarf_expr_context::get_frame_cfa): Remove
	method.
	* dwarf2/loc.c (dwarf_expr_context::get_frame_cfa): Remove
	method.
