Matt Arsenault 3dbeefa978 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).

Matt Arsenault 7aad8fd8f4 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.

Tom Stellard c2ff0eb697 AMDGPU/SI: Improve SILoadStoreOptimizer and run it before the scheduler
Summary:
The SILoadStoreOptimizer can now look ahead more then one instruction when
looking for instructions to merge, which greatly improves the number of
loads/stores that we are able to merge.

Moving the pass before scheduling avoids increasing register pressure after
the scheduler, so that the scheduler's register pressure estimates will be
more accurate.  It also gives more consistent results, since it is no longer
affected by minor scheduling changes.

Matt Arsenault 71e6676169 AMDGPU: Cleanup lowering actions
These are kind of a mess and hard to follow, particularly
for loads and stores. Fix various redundant, unnecessary
and dead settings.
