(preserve_values): Call it.
* value.h (value_of_internalvar): Add GDBARCH parameter.
(internalvar_make_value): Likewise.
* value.c (value_of_internalvar): Add GDBARCH parameter. Pass it to
make_value callback. Use it to generate per-architecture result value
types for internal variables with no pre-defined type. Update for data
structure changes.
(show_convenience): Pass architecture to value_of_internalvar.
* eval.c (evaluate_subexp_standard): Likewise.
* infrun.c (siginfo_make_value): Add GDBARCH parameter. Use it
instead of current frame architecture. Return per-architecture type.
* value.h (set_internalvar_string): Add prototype.
* value.c (set_internalvar_string): New function.
* tracepoint.c (set_traceframe_context): Use it.
