  [LICM] Support integer mul/add in hoistFPAssociation. (#67736)

The reassociation this is trying to repair can happen for integer types
too.

This patch adds support for integer mul/add to hoistFPAssociation. The
function has been renamed to hoistMulAddAssociation. I've used separate
statistics and limits for integer to allow tuning flexibility.
