Remove WebGPU support (#4108)
Leaves SPV_ENV_WEBGPU_0 enum in place, but marked deprecated, so users
of the library are not broken by an API enum being removed.

Validate location assignments (#3308)
* Add validation that input/output locations are assigned correctly
* Account for component assignment
* Account for 4 components per location and track the combined
coordinate
* Account for multiple output indexes
* handle specifically arrayed variables
* Arrayed variables that specify a component get locations determined
per index of the array for the sub type
  * Added tests that check locations and components can be assigned
  to interleave an array's locations and components
* Fix up which interfaces are allowed to be arrayed for various shader
stages based on glslang

5a48c0da15 SPIRV-Tools support for SPIR-V 1.5 (#2865)
* Ensure same enum values have consistent extension lists

* val: fix checking of capabilities

The operand for an OpCapability should only be
checked for the extension or core version.
The InstructionPass registers a capability, and all its implied
sub-capabilities before actually checking the operand to an
OpCapability.

* Add basic support for SPIR-V 1.5

- Adds SPV_ENV_UNIVERSAL_1_5
- Command line tools default to spv1.5 environment
- SPIR-V 1.5 incorporates several extensions.  Now the disassembler
  prefers outputing the non-EXT or non-KHR names.  This requires
  updates to many tests, to make strings match again.
- Command line tests: Expect SPIR-V 1.5 by default

* Test validation of SPIR-V 1.5 incorporated extensions

Starting with 1.5, incorporated features no longer require
the associated OpExtension instruction.

* Support --target-env spv1.4 in help for command line tools

* Support asm/dis of UniformId decoration

* Validate UniformId decoration

* Fix version check on instructions and operands

Also register decorations used with OpDecorateId

* Extension lists can differ between enums that match

Example: SubgroupMaskEq vs SubgroupMaskEqKHR

* Test asm/dis OpCopyMemory with 2-memory access

Add asm/dis tests for OpCopyMemorySized

Requires grammar update to add second optional memory access operand
to OpCopyMemory and OpCopyMemorySized

* Validate one or two memory accesses on OpCopyMemory*

* Check av/vis on CopyMemory source and target memory access

This is a proposed rule. See
https://gitlab.khronos.org/spirv/SPIR-V/issues/413

validate.  We need more context.

But we can make sure we allow the new image operands in known-good
cases.

1.4 environment

* Fix test for update to SPIR-V 1.4 headers

Restrict capabilities to WebGPU spec (#2113)
Restrict capabilities to WebGPU spec

This covers whitelisting Matrix, Shader, Sampled1D, Image1D,
DerivativeControl, and ImageQuery. These are the allowed capabilities
that don't require an extension. Whitelisting VulkanMemoryModelKHR
will be handled by whitelisting its extension in a seperate patch.

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.

363bfca2ed Operand lookup succeeds if it's enabled by a capability
- Fix tests for basic group operations (e.g. Reduce) to allow for
new capabilities in SPIR-V 1.3 that enable them.
- Refactor operand capability check to avoid code duplication and
to put all checks that don't need table lookup before any table
lookup.
- Test round trip assembly/disassembly support for extension
SPV_NV_viewport_array2
- Test assembly and validation of decoration ViewportRelativeNV

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.

83228137e1 Re-format source tree - NFC.
Re-formatted the source tree with the command:

$ /usr/bin/clang-format -style=file -i \
    $(find include source tools test utils -name '*.cpp' -or -name '*.h')

This required a fix to source/val/decoration.h.  It was not including
spirv.h, which broke builds when the #include headers were re-ordered by
clang-format.

d0620061c7 Adding validation code for more data rules.
These rules are under "Data Rules" in 2.16.1 (Universal Validation
Rules) part of the SPIR-V 1.1 Specification document:

* Scalar floating-point types can be parameterized only as 32 bit, plus
any additional sizes enabled by capabilities.

* Scalar integer types can be parameterized only as 32 bit, plus any
additional sizes enabled by capabilities.

* Vector types can only be parameterized with numerical types or the
OpTypeBool type.

* Matrix types can only be parameterized with floating-point types.

* Matrix types can only be parameterized as having only 2, 3, or 4
columns.

* Specialization constants (see Specialization) are limited to integers,
Booleans, floating-point numbers, and vectors of these.
