clang-p2996/llvm/test/Transforms/InstCombine/vec_shuffle.ll
Paul Walker fd07b8f809 [LLVM][tests/Transforms/InstCombine] Convert instances of ConstantExpr based splats to use splat(). 
This is mostly NFC but some output does change due to consistently
inserting into poison rather than undef and using i64 as the index
type for inserts.
