I see these failures on powerpc64-suse-linux.
pr37482.c seems to fail during expand of VEC_PERM_EXPR.
The accesses in vect-114.c are aligned, so it probably doesn't need
vect_hw_misalign (it was me who added it there
http://gcc.gnu.org/ml/gcc-patches/2010-11/msg01521.html, but it seems to be
incorrect).

The pr37482.c problem, at least, is a buffer overrun.

I'll fix vect-114.c. It indeed doesn't need realignment. The vectorization
failed before switching to optab because of the type mismatch between the mask
and the data.

pr37482 and vect114 seem OK now on powerpc-darwin9 (we have had bootstrap
problems - which are not cleared yet for some languages).
We also now have a large number of struct-layout-1, vmx and altivec fails
(possibly unrelated, will try and analyze tomorrow).

The failures are gone at revision 180100 with the the revisions given in
pr50778 reverted and the patch of revision 180106. So I am closing this pr as
fixed.
