Subject: [X86] EltsFromConsecutiveLoads - remove duplicate check for element size. NFCI.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=29c8649d15ff6e6d72407283767503a1bfdd0e49;p=llvm

[X86] EltsFromConsecutiveLoads - remove duplicate check for element size. NFCI.

We've already checked that each element is the correct contributory size for VT when we inspect the elements for Undef/Zero/Load.
