Hi,
Rebased the patch on top of Richard Sandiford's patches, with his fixes
I can now allow for vectorization of epilogues after we match simdlen.
This will however not turn on epilogue vectorization in cases where we
specify a desired simdlen that is never matched. This would require
more w

Hi,
I was using loop->simdlen to detect whether it was a SIMD loop and I
don't believe that was correct, as can be witnessed by the mass failures
in libgomp. My apologies for not running this, didn't think of it!
I found that these were failing because we do not handle vectorization
of epilo
