Arnold Schwaighofer ee3f7de62e LoopVectorizer: Handle strided memory accesses by versioning ...

for (i = 0; i < N; ++i)
   A[i * Stride1] += B[i * Stride2];

We take loops like this and check that the symbolic strides 'Strided1/2' are one
and drop to the scalar loop if they are not.

This is currently disabled by default and hidden behind the flag
'enable-mem-access-versioning'.
