From the Vulkan spec:
"VK_IMAGE_LAYOUT_DEPTH_STENCIL_READ_ONLY_OPTIMAL specifies a
layout for both the depth and stencil aspects of a depth/stencil
format image allowing read only access as a depth/stencil
attachment or in shaders as a sampled image, combined
image/sampler, or input attachment. It is equivalent to
VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_OPTIMAL and
VK_IMAGE_LAYOUT_STENCIL_READ_ONLY_OPTIMAL."
So, it should be safe to keep HTILE compressed if the depth/stencil
image isn't going to be sampled. We could probably extend this
to separate depth/stencil layout but that seems a bit more
complicated.
This gives a huge boost to the deferredmultisampling Vulkan demo.

A break/continue in a loop is typically emitted like this:
if (cond) {
break/continue;
} else {
}
If cond is uniform, we'll emit code for a uniform if statement and
that will emit a branch right before the if to jump directly to the
else (or the block after the else in this case, since the else is
empty) in case cond evaluates to false. This means we end up emitting
two consecutive branch instructions, one before the if and one for the
THEN block right after:
branch(!cond) -> jump to else (or after else) if cond is false
nop
nop
nop
branch -> unconditional jump to break/continue
nop
nop
nop
Instead, if we are in this scenario, we can do better by emitting the
conditional jump directly and avoiding the "jump to else" case:
branch(cond) -> jump to break/continue if cond is true
nop
nop
nop
We need to be careful when emitting the break/continue for the case
where all lanes are disabled to avoid infinite loops: if we have a
break we always want to take the jump, but we don't want to take it
if it is a continue.

Earlier, I just tried to copy what iris was doing and, as it turns out,
copied it wrong. Also, Vulkan doesn't have a concept of getting the
conservative coverage in the shader. The spec for SampleMask says:
"Decorating a variable with the SampleMask built-in decoration will
make any variable contain the coverage mask for the current fragment
shader invocation."
And the spec for conservative rasterization says
"When overestimate conservative rasterization is enabled, rather
than evaluating coverage at individual sample locations, a
determination is made of whether any portion of the pixel (including
its edges and corners) is covered by the primitive. If any portion
of the pixel is covered, then all bits of the coverage mask for the
fragment corresponding to that pixel are enabled."
Putting these two together and you get what the Intel HW docs say for
ICMS_NORMAL:
"Input Coverage masks based on inner conservatism and factors in
SAMPLE_MASKs. If Pixel is conservatively fully covered all samples
are enabled."
So I'm pretty sure based on this that the right thing to do here is to
ignore conservative rasterization and leave it set to ICMS_NORMAL
whenever we're not in the post-depth-coverage special case.
While we're here, fix the silly indentation.

Each call argument in the trace dump should be a separate <arg>
element. In this case the trace_dump_struct_array() needs to have
trace_dump_arg_begin() and trace_dump_arg_end() surrounding it,
otherwise it becomes just random data inside the parent call.
Also fix another case where one <arg> element erraneously contains
another <arg> element by moving trace_dump_arg_end() to its
proper place.
