This does not cause an issue currently, however if called differently to
their current usage, it can lead to an input being overwritten and
incorrect results being generated.

This provides significant performance gains for bn_sqr_comba4() and
bn_sqr_comba8().

This provides a performance gain across most BN operations.

This results in bn_mul_comba4() and bn_mul_comba8() requiring ~30% less
instructions than they did previously.

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.

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.

This will provide a location for machine specific defines, prototypes and
inline functions.
