New Revision: 71665

URL: http://llvm.org/viewvc/llvm-project?rev=71665&view=rev
Log:
Merge in 71640:

Fix rdar://6880951 by rejecting vectors of vectors.
It seems dubious to me that isIntegerType() returns true for
vectors of integers, but not complex integers.  This should 
probably be rethought, I'll file a bugzilla.
