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).

Un XFAIL a few tests plus a few more I had lying around
in my tree, which seem to all work now but I don't see tests
that quite test the same things.
