Björn Pettersson 26f5d1ee9c [APINotes] Avoid assertion failure with expensive checks (#120487) ...

Found assertion failures when using EXPENSIVE_CHECKS and running lit
tests for APINotes:
Assertion `left.first != right.first && "two entries for the same
version"' failed.

It seems like std::is_sorted is verifying that the comparison function
is reflective (comp(a,a)=false) when using expensive checks. So we would
get callbacks to the lambda used for comparison, even for vectors with a
single element in APINotesReader::VersionedInfo<T>::VersionedInfo, with
"left" and "right" being the same object. Therefore the assert checking
that we never found equal values would fail.

Fix makes sure that we skip the check for equal values when "left" and
"right" is the same object.
