a405c834e6 DAG: Fix not truncating when promoting bswap/bitreverse 
These need to convert back to the original type, like any
other promotion.

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.

8bc95d0a47 AMDGPU: Improve splitting 64-bit bit ops by constants 
This addresses a TODO to handle operations besides and. This
also starts eliminating no-op operations with a constant that
can emerge later.
