Ben Clayton 8ec32a6ec9 writers: Use the new sem::Module::DependencyOrderedDeclarations 
As the resolver currently enforces in-order declarations, this does not
change the declaration order from iterating over the
ast::Module::GlobalDeclarations.

The MSL backend has been changed to use the
sem::Module::DependencyOrderedDeclarations list instead of looping over
different declaration types separately.

Update validation error for invalid uniform array element alignment.

Update tests to either remove the @stride attribute or use a different
element type.

Ben Clayton cc05d89820 writer/msl: Replace use of 'auto' with actual return type 
Fixes MSL 1.2 error:
'auto' return without trailing return type; deduced return types are a C++14 extension

James Price e548db90f6 msl: Handle buffer variables in transform 
This removes a lot of awkward logic from the MSL writer, and means
that we now handle all module-scope variables with the same transform.

Ben Clayton 51cfe26bb7 writer/hlsl: Simplify UBO accesses for static indexing 
Use the new semantic constant value information to significantly reduce the complex indexing logic emitted for UBO accesses.
This will dramatically reduce the number of `for` loops that are decayed to `while` loops.
