d706d030af AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel 
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).

3081264dbe [AMDGPU] Remove getBidirectionalReasonRank 
This method inverts the Reason field of a scheduling candidate.
It does right comparison between RegCritical and RegExcess, but
everything else is broken. In fact it can prefer less strong reason
such as Weak over RegCritical because Weak > -RegCritical.

The CandReason enum is properly sorted, so just remove artificial
ranking.

4080a06a24 AMDGPU: Fix flat atomics 
The flat atomics could already be selected, but only
when using flat instructions for global memory. Add
patterns for flat addresses.
