Only safe if user knows that subsequent shader stage will not read clip
distance.

b29f83c383 MSL: Add options to control emission of fragment outputs.
Like with `point_size` when not rendering points, Metal complains when
writing to a variable using the `[[depth]]` qualifier when no depth
buffer be attached. In that case, we must avoid emitting `FragDepth`,
just like with `PointSize`.

I assume it will also complain if there be no stencil attachment and the
shader write to `[[stencil]]`, or it write to `[[color(n)]]` but there
be no color attachment at n.

fedbc35315 MSL: Support inline uniform blocks in argument buffers.
Here, the inline uniform block is explicit: we instantiate the buffer
block itself in the argument buffer, instead of a pointer to the buffer.
I just hope this will work with the `MTLArgumentDescriptor` API...

Note that Metal recursively assigns individual members of embedded
structs IDs. This means for automatic assignment that we have to
calculate the binding stride for a given buffer block. For MoltenVK,
we'll simply increment the ID by the size of the inline uniform block.
Then the later IDs will never conflict with the inline uniform block. We
can get away with this because Metal doesn't require that IDs be
contiguous, only monotonically increasing.

8bbb5fb763 Make SmallVector noexcept.
Fixes a linting error from cppcheck where reserve() calls can throw, but
caller is marked noexcept to allow proper move semantics.

Only real place to throw would be if allocations fail, but these
allocations tend to be small, and if allocation actually fails here,
we're basically OOM anyways, so just terminate. Constructors and assignment
could also fail, but the only way that could happen is memory related in
SPIRV-Cross' case, so just terminate if that happens as well.

Also, for good measure, add missing -fno-exceptions to EXCEPTIONS_TO_ASSERTIONS
path in CMake.

39dce88d3b MSL: Add support for sampler Y'CbCr conversion.
This change introduces functions and in one case, a class, to support
the `VK_KHR_sampler_ycbcr_conversion` extension. Except in the case of
GBGR8 and BGRG8 formats, for which Metal natively supports implicit
chroma reconstruction, we're on our own here. We have to do everything
ourselves. Much of the complexity comes from the need to support
multiple planes, which must now be passed to functions that use the
corresponding combined image-samplers. The rest is from the actual
Y'CbCr conversion itself, which requires additional post-processing of
the sample retrieved from the image.

Passing sampled images to a function was a particular problem. To
support this, I've added a new class which is emitted to MSL shaders
that pass sampled images with Y'CbCr conversions attached around. It
can handle sampled images with or without Y'CbCr conversion. This is an
awful abomination that should not exist, but I'm worried that there's
some shader out there which does this. This support requires Metal 2.0
to work properly, because it uses default-constructed texture objects,
which were only added in MSL 2. I'm not even going to get into arrays of
combined image-samplers--that's a whole other can of worms.  They are
deliberately unsupported in this change.

I've taken the liberty of refactoring the support for texture swizzling
while I'm at it. It's now treated as a post-processing step similar to
Y'CbCr conversion. I'd like to think this is cleaner than having
everything in `to_function_name()`/`to_function_args()`. It still looks
really hairy, though. I did, however, get rid of the explicit type
arguments to `spvGatherSwizzle()`/`spvGatherCompareSwizzle()`.

Update the C API. In addition to supporting this new functionality, add
some compiler options that I added in previous changes, but for which I
neglected to update the C API.

30bb197a5d MSL: Support remapping constexpr samplers by set/binding.
Older API was oriented around IDs which are not available unless you're
doing full reflection, which is awkward for certain use cases which know
their set/bindings up front.

Optimize resource bindings to be hashmap rather than doing linear seeks
all the time.

7b9e0fb428 MSL: Implement OpArrayLength.
This gets rather complicated because MSL does not support OpArrayLength
natively. We need to pass down a buffer which contains buffer sizes, and
we compute the array length on-demand.

eaf7afed97 MSL: Support argument buffers and image swizzling.
Change aux buffer to swizzle buffer.
There is no good reason to expand the aux buffer, so name it
appropriately.

Make the code cleaner by emitting a straight pointer to uint rather than
a dummy struct which only contains a single unsized array member anyways.

This will also end up being very similar to how we implement swizzle
buffers for argument buffers.

Do not use implied binding if it overflows int32_t.

9b92e68d71 Add an option to override the namespace used for spirv_cross.
This is a pragmatic trick to avoid symbol collision where a project
links against SPIRV-Cross statically, while linking to other projects
which also use SPIRV-Cross statically. We can end up with very awkward
symbol collisions which can resolve themselves silently because
SPIRV-Cross is pulled in as necessary. To fix this, we must use
different symbols and embed two copies of SPIRV-Cross in this scenario,
now with different namespaces, which in turn leads to different symbols.
