[PATCH] D34846: Remove Clang support for '-fvectorize-slp-aggressive' which used LLVM's basic block vectorizer. This vectorizer has had no known users for many, many years and is completely surpassed by the normal '-fvectorize-slp'-controlled SLP vectorizer in LLVM.

Removing a `-cc1` flag is OK: we explicitly tell people that the `-cc1` interface is subject to change without notice.
