Currently the default C calling convention functions are treated the same as compute kernels. Make this explicit so the default calling convention can be changed to a non-kernel. Converted with perl -pi -e 's/define void/define amdgpu_kernel void/' on the relevant test directories (and undoing in one place that actually wanted a non-kernel). llvm-svn: 298444

; The offset is apllied to the variables address at link time, which eliminates
|

; the need to emit shader instructions to do this calculation.
|

; We don't use relocations for local memory, so we should never fold offsets
