In the wake of https://reviews.llvm.org/D89559, we discovered that a
couple of tests (the ones modified below to have additional triple
versions) would fail on Win32, for 1 of two reasons. We seem to not
have a win32 buildbot anymore, so the triple is to make sure this
doesn't get broken in the future.
First, two of the three 'note-candidate' functions weren't appropriately
skipping the remaining conversion functions.
Second, in 1 situation (note surrogate candidates) we actually print the
type of the conversion operator. The two tests that ran into that
needed updating to make sure it printed the proper one in the win32
case.
