radeonsi: disable sinking common instructions down to the end block
Initially this was a workaround for a bug introduced in LLVM 4.0
in the SimplifyCFG pass that caused image instrinsics to disappear
(because they were badly sunk). Finally, this is a win because it
decreases SGPR spilling and increases the number of waves a bit.
Although, shader-db results are good I think we might want to
remove it in the future once the issue is fixed. For now, enable
it for LLVM >= 4.0.
This also fixes a rendering issue with the speedometer in Dirt Rally.
More information can be found here https://reviews.llvm.org/D26348.
Thanks to Dave Airlie for the patch.
v2: - add a FIXME comment
- use if (HAVE_LLVM >= 0x0400) instead
