But for the ABI conversion bits, these are just leaf functions and don't
even need unwind tables. Just renumber the registers on Windows to only
used volatile ones.
In doing so, this switches to writing rdrand explicitly. perlasm already
knows how to manually encode it and our minimum assembler versions
surely cover rdrand by now anyway. Also add the .size directive. I'm not
sure what it's used for, but the other files have it.
(This isn't a generally reusable technique. The more complex functions
will need actual unwind codes.)

This change syncs several assembly files from upstream. The only meanful
additions are more CFI directives.

Support for platforms that we don't support FIPS on doesn't need to be
in the module. Also, functions for dealing with whether fork-unsafe
buffering is enabled are left out because they aren't implementing any
cryptography and they use global r/w state, making their inclusion
painful.
