Prepare for future patch which affects codegen for calls to preemptible
functions.
Differential Revision: https://reviews.llvm.org/D57605
llvm-svn: 352920
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).
