Log:
Fix ICE in vect_slp_analyze_node_operations_1

This patch fixes bug 90681.  It was caused by trying to SLP vectorize a non
groupped load.  We've fixed it by tweaking a bit the implementation: mark
masked loads as not vectorizable, but support them as an special case.  Then
the detect them in the test for normal non-groupped loads that was already
there.
