Add MLIR SLP vectorizer to test in Wave. I hope it will eventually go upstream but for now let's keep it there. llvm/llvm-project#140469 Signed-off-by: Ivan Butygin <[email protected]>

Here is my attempt on SLP vectorizer for MLIR (using memref/arith/vector), mostly for fun. It is bidirectional, see code comments on implementation details.
@MaheshRavishankar @Groverkss @banach-space this is a follow-up to our euroLLVM vector roundtable discussion. I don't have an immediate usecase and mostly wrote this for self education, but maybe you find it useful.
