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).

When doing arcp optimization with a constant denominator,
this was leaving behind rcps with constant inputs.

This switches to the workaround that HSA defaults to
for the mesa path.
This should be applied to the 4.0 branch.

Summary:
GCNSchedStrategy re-uses most of GenericScheduler, it's just uses
a different method to compute the excess and critical register
pressure limits.
It's not enabled by default, to enable it you need to pass -misched=gcn
to llc.

Using rcp should be OK for safe math usually, so this
should not be replacing the original fdiv.

The intrinsic target prefix should match the target name
as it appears in the triple.
This is not yet complete, but gets most of the important ones.
llvm.AMDGPU.* intrinsics used by mesa and libclc are still handled
for compatability for now.
