no PC save.
This check does assume that the "PC register" is roughly a
traditional PC, even if the gdbarch_unwind_pc method adjusts
it (we do not rely on the value, only on the unwound PC being
dependent on this value). A potential improvement would be
to have the frame prev_pc method and the gdbarch unwind_pc
method set the same lval and location information as
frame_register_unwind. */
