  [LoopVectorize] Add test for follow-up metadata for loops (NFC) (#131337)

When pragma of loop transformations are encoded in LLVM IR, follow-up
metadata is used if multiple transformations are specified. They are
used to explicitly express the order of the transformations. However,
they are not properly processed on each transformation pass, so now only
the first one is attempted to be applied. This is a pre-commit to add a
test that causes the problem.
