Fix DW_OP_GNU_implicit_pointer for DWARF32 v3+ on 64-bit arches.
* dwarf2-frame.c (execute_stack_op): Initialize ctx->ref_addr_size.
* dwarf2expr.c (execute_stack_op) <DW_OP_GNU_implicit_pointer>: Use
ctx->ref_addr_size. Handle its invalid value.
* dwarf2expr.h (struct dwarf_expr_context): New field ref_addr_size.
* dwarf2loc.c (dwarf2_evaluate_loc_desc_full)
(dwarf2_loc_desc_needs_frame): Initialize ctx->ref_addr_size.
* dwarf2loc.h (dwarf2_per_cu_ref_addr_size): New declaration.
* dwarf2read.c (decode_locdesc): Initialize ctx->ref_addr_size.
(dwarf2_per_cu_ref_addr_size): New function.
