[mlir] Use interfaces in MathToLibm

Previously, this assumed use of ModuleOp and FuncOp. There is no need to
restrict this, and using interfaces allows these patterns to be used
during dialect conversion to LLVM.

Some assertions were removed due to inconsistent implementation of

[LoopDeletion] Consider infinite loops alive, unless mustprogress.

The current loop or any of its sub-loops may be infinite. Unless the
function or the loops are marked as mustprogress, this in itself makes
the loop *not* dead.

This patch moves the logic to check whether the current loop is finite
or mustprogress to `isLoopDead` and also extends it to check the
sub-loops. This should fix PR50511.
