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 87bc4c218b AMDGPU: Fix use-after-free in SIOptimizeExecMasking 
Summary:
There was a bug with sequences like

   s_mov_b64 s[0:1], exec
   s_and_b64 s[2:3]<def>, s[0:1], s[2:3]<kill>
   ...
   s_mov_b64_term exec, s[2:3]

because s[2:3] was defined and used in the same instruction, ending up with
SaveExecInst inside OtherUseInsts.

Note that the test case also exposes an unrelated bug.
