ia64: convert widen_[us]sum into convert optab [PR122069]

The target does not seem to have a maintainer listed, I've CC'ed a group of
global maintainers instead hoping one of you could approve it.

This patch is a mechanical rewrite of the widen_[us]sum optabs from a direct to
a conversion optab.  The result of which requires the output mode to be added to
the existing patterns.

No change in functionality is expected.
