The documentation for the "-mabi" argument on RISC-V was incorrect. We
chose to treat this as a documentation bug rather than a code bug, and
to make the documentation match what GCC currently does. In the
process, I also improved the documentation a bit.
Thanks to Alex Bradbury for finding the bug!

This patch adds helper functions that say which of the two modes
involved in a subreg is the larger, preferring the outer mode in
the event of a tie. It also converts IRA and reload to track modes
instead of byte sizes, since this is slightly more convenient when
variable-sized modes are added later.

The current frame code combines the separate concepts of a frame chain
(saving old FP,LR in a record and pointing new FP to it) and a frame
pointer used to access locals. Add emit_frame_chain to the aarch64_frame
descriptor and use it in the prolog and epilog code. For now just
initialize it as before, so generated code is identical.
Also correctly set EXIT_IGNORE_STACK. The current AArch64 epilog code
restores SP from FP if alloca is used. If a frame pointer is used but
there is no alloca, SP must remain valid for the epilog to work correctly.
