New Revision: 120694

URL: http://llvm.org/viewvc/llvm-project?rev=120694&view=rev
Log:
Add a test for calling a Neon intrinsic macro with the wrong vector type.
This does not work so well with the -fno-lax-vector-conversions option for
testing the arm_neon.h header but that is a really useful test, so I split
this out to a separate Sema test to check for the warning.
