[Bug middle-end/31699] [Regression 4.3] -march=opteron -ftree-vectorize generates wrong code

I'm testing the attched patch. The problem is that we don't compute the peel
factor correctly (when peeling to align a store) when we have multiple
data-types in the loop (the computation assumes that VF is the number of
elements in a vector, but that doesn't hold for all the datarefs in the loop if
their types are of different sizes)
