Code cleanupp: Use cu_offset and sect_offset compile time type checking. * dwarf2expr.c (add_piece, dwarf_get_base_type, execute_stack_op) (ctx_no_dwarf_call, ctx_no_get_base_type): Use cu_offset and sect_offset. * dwarf2expr.h (cu_offset, sect_offset): New types. (struct dwarf_expr_context_funcs) <dwarf_call> (struct dwarf_expr_context_funcs) <get_base_type>: Use cu_offset and sect_offset. (struct dwarf_expr_context) <len>: Improve the comment. (struct dwarf_expr_piece, ctx_no_dwarf_call, ctx_no_get_base_type): Use cu_offset and sect_offset. * dwarf2loc.c (per_cu_dwarf_call, dwarf_expr_dwarf_call) (dwarf_expr_get_base_type, needs_frame_dwarf_call) (dwarf2_compile_expr_to_ax, disassemble_dwarf_expression): Likewise. * dwarf2loc.h: Include dwarf2expr.h. (dwarf2_fetch_die_location_block, dwarf2_get_die_type): Use cu_offset and sect_offset. * dwarf2read.c (struct dwarf2_per_objfile) <debug_types_type_hash>: Improve the comment.
