[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.

LGTM

Per discussion on IRC, a follow-up patch from @nbjoerg will add the flag back 
with it just producing a warning that the flag has been removed and has no 
effect. While the usage of the driver flag is very low, the cost of keeping it 
around for compatibility is minuscule.
