The ImageMagick OpenCL Kernel

LLVM svn version: 325439
Mesa version: git fa8a764b62

The last version that worked was several weeks ago -- prior to the LLVM 6
branch.

The log is so short, I can paste it in here:

build options: -cl-single-precision-constant -cl-mad-enable
-DMAGICKCORE_HDRI_SUPPORT=1 -DCLQuantum=float -DCLSignedQuantum=float
-DCLPixelType=float4 -DQuantumRange=65535.000000 -DQuantumScale=0.000015
-DCharQuantumScale=1.000000 -DMagickEpsilon=0.000000 -DMagickPI=3.141593 
-DMaxMap=65535 -DMAGICKCORE_QUANTUM_DEPTH=16
<unknown>:0:0: in function AddNoise void (<4 x float> addrspace(1)*, <4 x
float> addrspace(1)*, i32, i32, i32, i32, float, i32, i32, i32): unsupported
initializer for address space

The unknown is because I have a stripped binary. I have not done all the manual
rebuilds for the symbols yet.

The actual kernel being compiled is attached. Hopefully it should be obvious
enough what the problem is.
