Note that this requires the shader info "tess" data to be correct.
For GLSL tess control shaders, only the output primitive count is
automatically available. The rest will need to be either guessed
or filled in from a matching tess eval (domain) shader. This is handled
by the d3d12 driver in a later patch.

Once we start writing multiple functions, we can't keep calling all

The instruction and block lists are moved into a new "function definition"
struct, and the DXIL module tracks one at a time for adding instructions
into. The NIR side still only emits the main function here though.

The resource declarations are module-wide, but the resource handles
are function-local. A future change will add multi-function support,
but requires these handles to be potentially emitted multiple times.
The alloca used for scratch is also function-local.
This is the same pattern that the DXBC to DXIL converter uses.

In the case of two vars being packed into the same register / location,
they'll still get unique driver_location, which is what we need.
This does require some tweaks to stream output handling, which also needs to
produce the varying index.

DXIL adds this in SM6.6, so when we get around to being able to
emit SM6.6, we can conditionally turn this off and support emitting
the new intrinsic. Until then, this is easy.

This *almost* matches what GLSL wants, except for the handling of
large widths. You can see this in the lowering algorithm:
(('bitfield_insert', 'base', 'insert', 'offset', 'bits'),
('bcsel', ('ult', 31, 'bits'), 'insert',
('bfi', ('bfm', 'bits', 'offset'), 'insert', 'base')),
'options->lower_bitfield_insert'),
DXIL's 'bfi' instruction is an inseparable pairing of NIR's 'bfi(bfm(...), ...)',
so we just apply the additional bcsel in the backend.

Note that GL requires input coverage for sample execution mode to
be only the single bit corresponding to the executing sample, so
rearrange things to understand during shader emitting if we're
executing per-sample to emit the right coverage value.

The first container stage ("build") is for dependencies of the build.
These are infrequently-changing things like Visual Studio, LLVM, git,
and also meson. The second container stage ("test") currently depends
on the first, and adds test dependencies like piglit.
This lets us rev piglit without having to rebuild LLVM.

This creates an internal shader_prim enum, I've fixed up most
users to use it instead of GL types.
don't store the enum in shader_info as it changes size, and confuses
other things.

This is a bit fragile. The algorithm is essentially:
- Let the driver track state for non-dual-bound resources.
- For resources that are dual-bound as SSBO/image and a second
bind point, assume they're being used as UAVs.
- When a MemoryBarrier is issued, dirty all destination bind points
so they re-assert their state, and if the destination is not UAV,
temporarily suppress UAV state re-assertion.

There are currently 3 different "environments" supported by this backend,
and they have slightly different semantics for how resources are accessed,
which is only going to get a little weirder when GL images start getting
supported. To try to make things less confusing, use an explicit enum
with heavy documentation on what's different between them.
