GS_FAST_LAUNCH=1 shouldn't be used on GFX11 but it's still needed for
dGPUs (eg. NAVI31) because it destroys performance for unknown reasons.
On RDNA3 APUs, GS_FAST_LAUNCH=2 seems to be required for working
mesh shaders and performance is fine. There is possibly a firmware bug
on APUs that would explain why GS_FAST_LAUNCH=1 doesn't work on Phoenix.

`EGL_EXT_query_reset_notification_strategy` complements
`EXT_create_context_robustness` and enables an application or framework to
retrieve an existing context's reset notification strategy in order to create
a compatible shared context.

Demoting means that we don't execute any writes to memory but
otherwise the invocation continues to execute. Particularly,
subgroup operations and derivatives must work.
Our implementation of discard does exactly this by using
setmsf to prevent writes for the affected invocations, the
only difference for us is that with discard/terminate we
want to be more careful with emitting quad loads for tmu
operations, since the invocations are not supposed to be
running any more and load offsets may not be valid, but with
demote the invocations are not terminated and thus we should
emit memory reads for them to ensure quad operations and
derivatives from invocations that have not been demoted still
work.
Since we use the sample mask to implement demotes we can't tell
whether a particular helper invocation was originally such
(gl_HelperInvocation in GLSL) or was later demoted
(OpIsHelperInvocationEXT added with SPV_EXT_demote_to_helper_invocation),
so we use nir_lower_is_helper_invocation to take care of this.

This is highly experimental and only recommended
for users who know what they are doing.
To fully support the spec we are going to need
gang submissions which are going to be implemented later.

Developers can limit supported modifers to a single
modifier provided in INTEL_MODIFIER_OVERRIDE environment
variable for debug purposes. For example, setting it
makes Vulkan CTS only run modifier tests against the
specified modifier instead of all modifiers in production
code.

A write mask based on the pipeline creation input is stored in scratch. Another
similar mask is also stored for the dynamic color_write_enable. These can then
be updated individually, and will be combined in MME macro before use.
Each attachment has a mask for rgba. The max number of attachments in 8 so
we can fit the write mask in a single 32bit scratch.
color_write_enable is a single bit per attachment. To make it easier to combine
in with the write mask it is stored in scratch with a separate rgba bits.
The layout of the both scratch values are:
