V(_Montgomery, _mulMod, Montgomery_mulMod, 149127024)
should be added as well. It is technically part of Bigint (used for modPow, e.g.
in RSA benchmark).

I'll add it in my next cl.

Little twist: no intrinsic for _estQuotientDigit is provided on arm or mips,
because no 64-bit by 32-bit division instruction exists on these platforms.
Prohibiting inlining is therefore not optimal in that particular case. Since a
runtime call will be used for the division, it probably does not matter.
