[InstCombine] Support reassoc for foldLogicOfFCmps (#116065)
We currently support simple reassociation for foldAndOrOfICmps().
Support the same for foldLogicOfFCmps() by going through the common
foldBooleanAndOr() helper.
This will also resolve the regression on #112704, which is also due to
missing reassoc support.
I had to adjust one fold to add support for FMF flag preservation,
otherwise there would be test regressions. There is a separate fold
(reassociateFCmps) handling reassociation for *just* that specific case
and it preserves FMF. Unfortunately it's not rendered entirely redundant
by this patch, because it handles one more level of reassociation as
well.
