This should also return a flag saying whether to keep the new
frame, or whether to discard it, because on some machines (e.g.
mips) it is really awkward to have FRAME_CHAIN_VALID called
BEFORE DEPRECATED_INIT_EXTRA_FRAME_INFO (there is no good way to
get information deduced in FRAME_CHAIN_VALID into the extra

means that the convolution below - needing to carefully order a
frame's initialization - isn't needed.
The irony here though, is that FRAME_CHAIN(), at least for a more
up-to-date architecture, always calls FRAME_SAVED_PC(), and
FRAME_SAVED_PC() computes the PC but without first needing the
frame! Instead of the convolution below, we could have simply
called FRAME_SAVED_PC() and been done with it! Note that
FRAME_SAVED_PC() is being superseed by frame_pc_unwind() and that
function does have somewhere to cache that PC value. */
