This patch adds scalar/subvector BROADCAST handling to EltsFromConsecutiveLoads.
It mainly shows codegen changes to 32-bit code which failed to handle i64 loads, although 64-bit code is also using this new path to more efficiently combine to a broadcast load.
@craig.topper I was trying to see whether I could get AVX512 i64 broadcast folds to work for 32-bit targets but didn't have much success - any ideas? I guess i686 is not that high priority....
