Validate variable types for UniformConstant storage in Vulkan (#2008) (#2044)
Validate variable types for UniformConstant storage in Vulkan (#2008)

From the Vulkan 1.1 spec 14.5.2:
  Variables identified with the UniformConstant storage class are used
  only as handles to refer to opaque resources. Such variables must be
  typed as OpTypeImage, OpTypeSampler, OpTypeSampledImage, or an array
  of one of these types.

Fixes #2008

a77bb2e54b Add validation for execution modes
* Check rules from Execution Mode tables, 2.16.2 and the Vulkan
environment spec

* Allows MeshNV execution model with the following execution modes
 * LocalSize, LocalSizeId, OutputPoints and OutputVertices
 * Done to not break their validation

ba602c9059 Add a WIP WebGPU environment. It disallows OpUndef
Add SPV_ENV_WEBGPU_0 for work-in-progress WebGPU.

val: Disallow OpUndef in WebGPU env

Silence unused variable warnings when !defined(SPIRV_EFFCE)

Limit visibility of validate_instruction.cpp's symbols
  Only InstructionPass needs to be visible so all other functions are put
  in an anonymous namespace inside the libspirv namespace.

8d65c89678 Instruction lookup succeeds if it's enabled by a capability
Also add a corresponding check for capabilities in the validator.

Update previously existing test cases where an instruction used to fail
assembling because of a version check, but now they succeed because the
instruction is also guarded by a capability.  Now it should assemble.
Add tests to ensure that capabilities are checked appropriately.

The explicitly reserved instructions OpImageSparseSampleProj*
now assemble, but they fail validation.

Fixes #1624

4f866abfd8 Validate static uses of interfaces
Fixes #1120

Checks that all static uses of the Input and Output variables are listed
as interfaces in each corresponding entry point declaration.
 * Changed validation state to track interface lists
 * updated many tests
* Modified validation state to store entry point names
 * Combined with interface list and called EntryPointDescription
 * Updated uses
* Changed interface validation error messages to output entry point name
in addtion to ID

700ebd3442 Make fewer test executables
Try to reduce the amount of disk space used by especially by debug builds,
which may be contributing to AppVeyor failures.

Collapses tests in categories:
- validator
- loop optimizations
- dominator analysis
- linker

Contributes to #1615

fe9121f721 Add Vulkan validation rules for BuiltIn variables
Added a framework for validation of BuiltIn variables. The framework
allows implementation of flexible abstract rules which are required for
built-ins as the information (decoration, definition, reference) is not
in one place, but is scattered all over the module.

Validation rules are implemented as a map
id -> list<functor(instrution)>

Ids which are dependent on built-in types or objects receive a task
list, such as "this id cannot be referenced from function which is
called from entry point with execution model X; propagate this rule
to your descendants in the global scope".

Also refactored test/val/val_fixtures.

All built-ins covered by tests

1ef6b19260 Migrate to use unified grammar tables
Previously we keep a separate static grammar table for opcodes/
operands per SPIR-V version. This commit changes that to use a
single unified static grammar table for opcodes/operands.

This essentially changes how grammar facts are queried against
a certain target environment. There are only limited filtering
according to the desired target environment; a symbol is
considered as available as long as:

1. The target environment satisfies the minimal requirement of
   the symbol; or
2. There is at least one extension enabling this symbol.

Note that the second rule assumes the extension enabling the
symbol is indeed requested in the SPIR-V code; checking that
should be the validator's work.

Also fixed a few grammar related issues:
* Rounding mode capability requirements are moved to client APIs.
* Reserved symbols not available in any extension is no longer
  recognized by assembler.

68e36ec7e9 Introducing a new flow for running the Validator.
We are adding a new API which can be called to run the SPIR-V validator,
and retrieve the ValidationState_t object. This is very useful for
unit testing.

I have also added basic unit tests that demonstrate usage of this flow
and ease of use to verify correctness.

bd5b0bfca1 Checks that result IDs are within the ID bound specified in the SPIR-V header
This is described in Section 2.17 of the SPIR-V Spec.

* Updated existing unit test 'SemanticsIdIsAnIdNotALiteral' to pass by
manipulating the ID bound in its binary header.

* Fixed boundary check in the code.

* Added unit test to check the case that the largest ID is equal to the
ID bound.
