Graham Hunter 6f1a8c2da2 [LV] Vectorize histogram operations (#99851) ...

This patch implements autovectorization support for the 'all-in-one'
histogram intrinsic, which seems to have more support than the
'standalone' intrinsic. See
https://discourse.llvm.org/t/rfc-vectorization-support-for-histogram-count-operations/74788/
for an overview of the work and my notes on the tradeoffs between the
two approaches.
