8538b4c9c0 Handle empty struct declarations with best effort.
This "feature" is a bit icky as we have no useful representation of it,
so never emit code which has anything to do with empty structs.

b2c2e6483b Analyze parameter preservation for functions.
This is kinda tricky, because if we only conditionally write to a

be4cb17a14 Enhance MSL testing and add numerous MSL test cases.
Add to suite of MSL tests and references any existing GLSL tests
that successfully convert GLSL->SPIRV->MSL and compile as MSL.
test_shaders_helper() ignores hidden files that start with '.',
to avoid accidentally finding hidden OSX files such as .DS_Store.
Use xcrun to compile MSL shaders instead of hard-coded path to Metal compiler.
Wrap calls to xcrun in exception handling to ignore if Xcode not installed.
For MSL tests, move call to validate_shader_msl() to after call to
regression_check() to allow a converted MSL shader to be saved for
manual review even if it doesn't successfully compile as MSL.

f45075b08b Validate Metal shaders on OSX with Metal compiler
If we run on a system with Xcode installed to a default path, run Xcode
Metal shader compiler to validate the generated MSL shader.

This uncovers an issue in the existing MSL test - MSL backend currently
does not auto-assign attribute locations, which means that translating
GLSL shader without location layout produces an invalid MSL which
generates "error: 'attribute' index '0' is used more than once".

ed04c95b08 Implement flattening of row major matrix indexing
To extract a column from row-major matrix, we need to do a strided load one
component at a time. In this case flattened_access_chain_offset still returns
the offset to the first element, but the stride is equal to matrix stride
instead of vector stride.

For this to work, we need to pass matrix stride (and transpose flag) through,
similar to how matrix flattening works.

Additionally slightly clean up recursive flattened_access_chain structure -
specifically, instead of deciding mid-traversal that we need matrix stride
information, we can just pass the matrix stride through - for access chains
that end in matrix/vector this gets us what we need, and for access chains
that end in structs the flattened_access_chain_struct code will recompute
correct stride/transposition data to pass through further.

62b27f1d81 Implement access chain flattening support for row major matrices
We currently only support access chains that end in a matrix by propagating
"needs transpose" flag upstream which flips the matrix multiplication order.

It's possible to support indexed extraction as well, however it would have to
generate code like this:

    vec4 row = vec4(UBO[0].y, UBO[1].y, UBO[2].y, UBO[3].y);

for a column equivalent of:

    vec4 row = UBO[1];

It is definitely possible to do so but it requires signaling the vector output
that it needs to switch to per-component extraction which is a bit more trouble
than this is worth for now.
