ah.  Fails with -O1 -ftree-vectorize, works with -O2 -ftree-vectorize on trunk.

Appears that we allocate memory (via get_secondary_mem) after the point at
which we believe the size of frame should be fixed.  This would tend to
indicate that during find_reloads we thought no secondary memory was needed,
but then later decided it was needed.  That's clearly bad.
