This updates https://reviews.llvm.org/D120329 to the changed interface of
https://reviews.llvm.org/D120327.

In particular:

- We call __udivmodei5 / __divmodei5 instead of __divei4,__udivei4,__modei4,__umodei4 to avoid requiring dynamic allocation
- __udivmodei5/__divmodei5 take the number of words instead of number of bits as argument
- The argument 'a' needs to hold on extra word to allow for implementations that need that scratch space
