[InstCombine] Infer nusw + nneg -> nuw for getelementptr (#111144 )

If the gep is nusw (usually via inbounds) and the offset is
non-negative, we can infer nuw.

[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.
