Brian Smith 7fcbfdbdf3 Calculate inverse in |BN_MONT_CTX_set| in constant time w.r.t. modulus.
Simplify the calculation of the Montgomery constants in
|BN_MONT_CTX_set|, making the inversion constant-time. It should also
be faster by avoiding any use of the |BIGNUM| API in favor of using
only 64-bit arithmetic.

Now it's obvious how it works. /s
