* add support for zero value constructors and constructors that infer their type from their parameters
* address comments
* extract constructor machinery into new module
* fix doc link
- samplerCubeShadow requires vec3 gradients
- Bias must be written after offset
- sampler1D hack on GLES requires vec2 gradients
- textureSize doesn't accept a lod argument for MS samplers
- sampler1DArray hack on GLES requires a y component on imageLoad
This one grew out of hand quick. Initially it was just replacing the bit
loops with a function driving the declarations to make the code sharing
better and support different scalar kinds.
Now it includes a lot of fixes:
- `textureSize` now also returns the array layers as the last component
on the return (only for arrayed textures)
- `textureSize` now supports multisampled textures
- the `texture` family of functions now consumes a `vec3` coordinate
vector for all 1D shadow textures
- Shadow textures can use the bias version of `texture` functions
(temporarily disabled since naga doesn't support it)
- 3D textures can be used in `textureProj`
- `sampler2DArrayShadow` can't be used in `textureLod` or in `texture` with bias
- Cube textures cannot be used with offsets
Updates the tests to cover all functions
The _buffer_sizes argument should be inserted regardless of whether or not `
`options.fake_missing_bindings` is set, so lift the computation of
`supports_array_length` out of that conditional.
The previous implementation had many issues, most importantly it didn't
allow to implement (at least in a sane way) some future features like
default qualifiers and format qualifiers.
This implementations centralizes the qualifiers into a struct with a
hashmap for layout qualifiers, error reporting is also centralized which
means that `add_global_var` and `add_local_var` no longer need to
duplicate effort and the ugly loop + match combo is gone.
Finally some minor fixes are also done as part of this rework, like
a default location being provided for input/outputs variables and layout
qualifiers being allowed to be repeated (overwriting the previous one)
like the spec defines.

* Added a test case
* Fix the test
* Changes to baking of expressions, incl args of integer dot product
* Implemented requested changes for glsl backend
* Added support for integer dot product on MSL backend
* Removed outdated code for hlsl and wgls writers
* Implement in spv backend
* Commit modified outputs from running the tests
* cargo fmt
* Applied requested changes for both MSL and GLSL back
* Changes to spv back
* Committed all test output changes
* Cargo fmt
* Added a comment w.r.t. VK_KHR_shader_integer_dot_product

This is because I wanted to highlight the fact that the correct
id is used in the last sum of the integer dot product expression
