* ax-gdb.h (struct axs_value): New field optimized_out.
(gen_trace_for_var): Add gdbarch argument.
* ax-gdb.c (gen_trace_static_fields): New function.
(gen_traced_pop): Call it, add gdbarch argument.
(gen_trace_for_expr): Update call to it.
(gen_trace_for_var): Ditto, and report optimized-out variables.
(gen_struct_ref_recursive): Check for optimized-out value.
(gen_struct_elt_for_reference): Ditto.
(gen_static_field): Pass gdbarch instead of expression, assume
optimization if field not found.
(gen_var_ref): Set the optimized_out flag.
(gen_expr): Error on optimized-out variable.
* tracepoint.c (collect_symbol): Handle struct-valued vars as
expressions, skip optimized-out variables with computed locations.
* dwarf2loc.c (dwarf2_tracepoint_var_ref): Flag instead of
erroring out if location expression missing.
(loclist_tracepoint_var_ref): Don't error out here.
