Reviewers: Benedikt Meurer,
Message:
The call sites could be nicer, but I want to land this drop-in replacement
first
before doing any more cleanup. Real unit tests can be added later, even
exhausting testing of the 32bit variants is relatively quick when doing
multi-threaded on our workstations.
Somehow I feel that assembler.{h,cc} is not a nice place for these classes,
better suggestions welcome...
Description:
Generalized division via multiplication.
We can now compute the magic numbers for all combinations of 32bit and
64bit (un)signed multiplications.
