This doesn't need a PR. Just commit the (pre-approved) obvious patch.

Note that in addition to spurious "inexact" exceptions, this division can cause
spurious "underflow" exceptions when converting tiny values to integer 0.
Other spurious exceptions can occur in overflow cases, when only "invalid"
should be raised, and the signed conversions wrapping this function can fail to
raise "invalid" for some overflow cases.
