Log message:
Improve bn_montgomery_multiply_words()
Pull a number of invariants into variables, which avoids repeated loading
from memory on architectures where sufficient registers are available.
Also keep track of the per-iteration carry in a variable, rather than
unnecessarily reading from and writing to memory.
This gives a reasonable performance gain on some architectures (e.g. armv7)
