gcc13-pr106652-wip.patch

Further updated patch which implements also the 4) diagnostics, both for binary
operations and ?: and punts in c-common.c uses if common_type fails, plus an
added x86 specific tests for further errors and a powerpc specific test to test
for the long double (IBM extended) vs. _Float128 unordered conversion ranks.
[over.ics.rank] changes are still not implemented and I'm lost there.
