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.

Nicolai Haehnle ce2b589df5 AMDGPU: Fix legalization of MUBUF instructions in shaders
Summary:
The addr64-based legalization is incorrect for MUBUF instructions with idxen
set as well as for BUFFER_LOAD/STORE_FORMAT_* instructions.  This affects
e.g.  shaders that access buffer textures.

Since we never actually need the addr64-legalization in shaders, this patch
takes the easy route and keys off the calling convention.  If this ever
affects (non-OpenGL) compute, the type of legalization needs to be chosen
based on some TSFlag.
