[AArch64] Lower scalable i1 vector add reduction to cntp (#100118)
Doing an add reduction on a vector of i1 elements is the same as
counting the number of set elements so such a reduction can be lowered
to a cntp instruction. This saves a number of instructions over
performing a UADDV. This patch only handles straightforward cases (i.e.
when vectors are not split).
