Michael Kuperstein e1ab454f4d [LV] Remove triples from target-independent vectorizer tests. NFC.
Vectorizer tests in the target-independent directory should not have a target
triple. If a test really needs to query a specific backend, it belongs in the
right target subdirectory (which "REQUIRES" the right backend). Otherwise, it
should not specify a triple.
