* Disallow loading a runtime-sized array
Fixes#4472
* Disallow loading a runtime-sized array or a composite containing one
* Refactor type traversal into a separate function used by both runtime
array checks and sized int/float checks
* Update invalid tests
* Initial support for SPV_KHR_integer_dot_product
- Adds new operand types for packed-vector-format
- Moves ray tracing enums to the end
- PackedVectorFormat is a new optional operand type, so it requires
special handling in grammar table generation.
- Add SPV_KHR_integer_dot_product to optimizer whitelists.
- Pass-through validation: valid cases pass validation
Validation errors are not checked.
- Update SPIRV-Headers

PR #4118 (d71ac38b8e) let spirv-val report a validation error when we
use offset for an OpImage* instruction instead of ConstantOffset. Since
some compilers like DXC rely on spirv-opt for function inlining or loop
unrolling, the spirv-val change broke some working shaders when the
shader developers disable the optimization (spirv-opt).
For example, DXC recently got this issue from a few users e.g.,
https://github.com/microsoft/DirectXShaderCompiler/issues/3807
Since this error is reported only when the spirv-opt is disabled, it
looks like the exact case that we have to skip spirv-val when
`--before-legalize-hlsl` is given. Moreover, avoiding the error using
`--before-legalize-hlsl` on DXC is exactly what FXC and DXC's DXIL
do (they do not report the error if the offset becomes a constant after
function inlining or loop unrolling).

* When a loop has an empty loop construct, the loop construct and
continue construct share the same header so don't disallow the loop
header for the continue construct
This pass converts an internal form of GLSLstd450 Interpolate ops
to the externally valid form. The external form takes the lvalue
of the interpolant. The internal form can do a load of the interpolant.
The pass replaces the load with its pointer. The internal form is
generated by glslang and possibly other frontends for HLSL shaders.
The new pass is called as part of HLSL legalization after all
propagation is complete.
Also adds internal interpolate form to pre-legalization validation
* Validate SPV_KHR_workgroup_memory_explicit_layout
* Check if SPIR-V is at least 1.4 to use the extension.
* Check if either only Workgroup Blocks or only Workgroup non-Blocks
are used.
* Check that if more than one Workgroup Block is used, variables are
decorated with Aliased.
* Check layout decorations for Workgroup Blocks.
* Implicitly use main capability if the ...8BitAccess or
...16BitAccess are used.
* Allow 8-bit and 16-bit types when ...8BitAccess and ...16BitAccess
are used respectively.
* Update SPIRV-Headers dependency
Bump it to include SPV_KHR_workgroup_memory_explicit_layout.
* Add option to validate Workgroup blocks with scalar layout
Validate the equivalent of scalarBlockLayout for Workgroup storage
class Block variables from SPV_KHR_workgroup_memory_explicit_layout.
Add option to the API and command line tool.
