Runs into issues with gcc.target/i386/l_fma_double_1.c and friends
because that now does peeling for alignment instead of just versioning
for alias. And peeling for alignment is only applied on x86_64 for
double because on i686 alignment might not be reachable with peeling.
Trying to fixup in the testcase with a properly aligned double type
shows that we don't honor user alignment in the vectorizer for this
purpose - thus, fixed, to allow not too ugly adjustments of
the fma testcases.
Bootstrapped and tested on x86_64-unknown-linux-gnu, applied to trunk.
