[SLPVectorizer] Set flag to previous default. 

Summary:
The refactoring in r360276 moved the `RunSLPVectorization` flag and added the default explicitly. The default should have been `false`, as before.

The new pass manager used to have SLPVectorization on by default, now it's off in opt, and needs D61617 checked in to enable it in clang.
