Arnold Schwaighofer 06413cd0f0 LoopVectorizer: Add a check that the backedge taken count + 1 does not overflow
The loop vectorizer instantiates be-taken-count + 1 as the loop iteration count.
If this expression overflows the generated code was invalid.

In case of overflow the code now jumps to the scalar loop.

Fixes PR17288.
