Matthias Gehre 6d13b80fcb Revert "[SelectionDAG] Emit calls to __divei4 and friends for division/remainder of large integers" ...

This reverts https://reviews.llvm.org/D120329.
I abandoned the PR [0] to add __divei4 functions to compiler-rt
in favor of adding a pass to transform div/rem [1].

This removes the backend code that was supposed to emit calls to the __divei4 functions.
