When the scratch ringbuffer settings are changed, the shader unit has
to be idle or we will have shaders using old and new settings.
That combination is not supported on the HW (likely the offset is
ringbuffer idx * WAVESIZE * 1024).

This extension allows to use subgroup operations with 8 and 16-bits
Untested on GFX6-GFX7, and most of subgroup operations are broken

This actually supports more of the extension than the LLVM backend but we
can't enable it because ACO doesn't work with all stages yet.
With more of it enabled, some CTS tests fail because our 64-bit sqrt
is very imprecise. I can't find any precision requirements for it
anywhere, so I'm thinking it might be a CTS issue.

Previously, instruction selection had two kinds of booleans:
1. divergent which was per-lane and stored in s2 (VCC size)
2. uniform which was stored in s1
Additionally, uniform booleans were made per-lane when they resulted
from operations which were supported only by the VALU.
To decide which type was used, we relied on the destination size,
which was not reliable due to the per-lane uniform bools, but it
mostly works on wave64.
However, in wave32 mode (where VCC is also s1) this approach
makes it impossible keep track of which boolean is uniform and
which is divergent.
This commit makes all booleans per-lane.
The resulting excess code size will be taken care of by the optimizer.

This extension allows to control the subgroup size by allowing a
varying subgroup size and also specifying a required subgroup size.
This implementation only allows to specify a required subgroup
size for compute shaders because there is some caveats with
other shader stages (eg. NGG with geometry shader). This
basically allows apps to use Wave32 for compute shaders.
This extension is enabled for all chips but only GFX10 supports
Wave32. ACO doesn't support it.
