Commit 7f152543e4ff91f2ce8578a1b3b3ec18f580345a by gil.rapaport [LV] Apply sink-after & interleave-groups as VPlan transformations (NFCI) This recommits 11ed1c0239fd51fd2f064311dc7725277ed0a994 (reverted in 9f08ce0d2197d4f163dfa4633eae2347ce8fc881 for failing an assert) with a fix: tryToWidenMemory() now first checks if the widening decision is to interleave, thus maintaining previous behavior where tryToInterleaveMemory() was called first, giving priority to interleave decisions over widening/scalarization. This commit adds the test case that exposed this bug as a LIT.
