This keeps the naming consistent with the other bignum primitives that have
been recently introduced. Also, use 1/0 intead of h/l (e.g. a1 instead of
ah), as this keeps consistency with other primitives and allows for naming
that works with double word, triple word and quadruple word inputs/outputs.

Fix output constraints for bn_umul_hilo().2023-02-04T11:48:55+00:00jsing2023-02-04T11:48:55+00:00urn:sha1:6c95a9f285330e88fd5a77d363441327b6d42630
When bn_umul_hilo() is implemented using an instruction pair, mark the
first output with a constraint that prevents the output from overlapping
with the inputs ("&"). Otherwise the first instruction can overwrite the
inputs, which then results in the second instruction producing incorrect
value.
Provide inline assembly bn_umul_hilo() for alpha/powerpc64/riscv64.2023-01-31T05:57:08+00:00jsing2023-01-31T05:57:08+00:00urn:sha1:679f8c4daf382efeee02c91cc81af88941779b9f
These should work, but are currently untested and disabled.

Provide a per machine bn_arch.h.2023-01-20T10:04:34+00:00jsing2023-01-20T10:04:34+00:00urn:sha1:481d4dbec5e67fc8e767c554b19a84590c6c755f
This will provide a location for machine specific defines, prototypes and
inline functions.
