d74d012b62 AMDGPU: Start selecting global instructions

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).

d019e8638a Enable FeatureFlatForGlobal on Volcanic Islands
This switches to the workaround that HSA defaults to
for the mesa path.

This should be applied to the 4.0 branch.

03ca6fb151 AMDGPU: Define priorities for register classes
Allocating larger register classes first should give better allocation
results (and more importantly for myself, make the lit tests more stable
with respect to scheduler changes).

aced110517 AMDGPU/SI: Fix s_waitcnt insertion for flat instructions
Summary:
This was broken in r260694 which swapped the address and data operands
for flat store instructions.  The code in SIInsertWaits assumes
that the data operand always comes before the address operand, so
we need to add a special case for flat.
