Brian Smith d1425f69df Simplify division-with-remainder calculations in crypto/bn/div.c. 
Create a |bn_div_rem_words| that is used for double-word/single-word
divisions and division-with-remainder. Remove all implementations of
|bn_div_words| except for the implementation needed for 64-bit MSVC.
This allows more code to be shared across platforms and also removes
an instance of the dangerous pattern wherein the |div_asm| macro
modified a variable that wasn't passed as a parameter.

Also, document the limitations of the compiler-generated code for the
non-asm code paths more fully. Compilers indeed have not improved in
this respect.
