PUSH_ROUNDING is difficult to convert to a hook since there is still
a lot of conditional code based on it. It isn't clear that a direct
conversion with checks for null hooks is the right thing to do.
Rather than untangle that, this patch converts all implementations
that do something to out-of-line functions that have the same
interface as a hook would have. This should at least help towards
any future hook conversion.
