New Revision: 119742

URL: http://llvm.org/viewvc/llvm-project?rev=119742&view=rev
Log:
Change the 'x' type modifier for Neon intrinsics to force a signed integer.
This makes it symmetric with the 'u' modifier that forces an unsigned type.
This is needed for unsigned vector shifts, where the shift amount still needs
to be signed.  PR8482 (Radar 8603521).
