Improve decoration validation (#4490)
Fixes #4469

* Checks that decorations only usable with structure members are not
  used by OpDecorate or OpDecorateId
* Checks that decorations not allowed on structure members are not used
  with OpMemberDecorate
* Checks decoration targets for most core decorations
* Performs some Vulkan specific validation on deorations

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.

Fixes #4101

Add support for SPV_KHR_non_semantic_info (#3110)
Add support for SPV_KHR_non_semantic_info

This entails a couple of changes:

- Allowing unknown OpExtInstImport that begin with the prefix `NonSemantic.`
- Allowing OpExtInst that reference any of those sets to contain unknown
  ext inst instruction numbers, and assume the format is always a series of IDs
  as guaranteed by the extension.
- Allowing those OpExtInst to appear in the types/variables/constants section.
- Not stripping OpString in the --strip-debug pass, since it may be referenced
  by these non-semantic OpExtInsts.
- Stripping them instead in the --strip-reflect pass.

* Add adjacency validation of non-semantic OpExtInst

- We validate and test that OpExtInst cannot appear before or between
  OpPhi instructions, or before/between OpFunctionParameter
  instructions.

* Change non-semantic extinst type to single value

* Add helper function spvExtInstIsNonSemantic() which will check if the extinst
  set is non-semantic or not, either the unknown generic value or any future
  recognised non-semantic set.

* Add test of a complex non-semantic extinst

* Use DefUseManager in StripDebugInfoPass to strip some OpStrings

* Any OpString used by a non-semantic instruction cannot be stripped, all others
  can so we search for uses to see if each string can be removed.
* We only do this if the non-semantic debug info extension is enabled, otherwise
  all strings can be trivially removed.

* Silence -Winconsistent-missing-override in protobufs

Process OpDecorateId in ADCE (#2761)
* Process OpDecorateId in ADCE

When there is an OpDecorateId instruction that is live,
the ids that is references must be kept live.  This change
adds them to the worklist.

I've also updated a validator check to allow OpDecorateId
to be able to apply to decoration groups.

Fixes #1759.

* Remove dead code.

Support SPIR-V 1.4 (#2550)
* SPIR-V 1.4 headers, add SPV_ENV_UNIVERSAL_1_4

* 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

* Validate scope value for Uniform decoration, for SPIR-V 1.4

* More unioning of exts

* Preserve grammar order within an enum value

* 1.4: Validate OpSelect over composites

* Tools default to 1.4

* Add asm/dis test for OpCopyLogical

* 1.4: asm/dis tests for PtrEqual, PtrNotEqual, PtrDiff

* Basic asm/Dis test for OpCopyMemory

* 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 operation for OpSpecConstantOp

* Validate NonWritable decoration

Also permit NonWritable on members of UBO and SSBO.

* SPIR-V 1.4: NonWrtiable can decorate Function and Private vars

* Update optimizer CLI tests for SPIR-V 1.4

* Testing tools: Give expected SPIR-V version in message

* SPIR-V 1.4 validation for entry point interfaces

* Allow only unique interfaces
* Allow all global variables
* Check that all statically used global variables are listed
* new tests

* Add validation fixture CompileFailure

* Add 1.4 validation for pointer comparisons

* New tests

* Validate with image operands SignExtend, ZeroExtend

Since we don't actually know the image texel format, we can't fully
validate.  We need more context.

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

* Validate OpCopyLogical

* Recursively checks subtypes
* new tests

* Add SPIR-V 1.4 tests for NoSignedWrap, NoUnsignedWrap

* Allow scalar conditions in 1.4 with OpSelect

* Allows scalar conditions with vector operands
* new tests

* Validate uniform id scope as an execution scope

* Validate the values of memory and execution scopes are valid scope
values
* new test

* Remove SPIR-V 1.4 Vulkan 1.0 environment

* SPIR-V 1.4 requires Vulkan 1.1

* FIX: include string for spvLog

* FIX: validate nonwritable

* FIX: test case suite for member decorate string

* FIX: test case for hlsl functionality1

* Validation test fixture: ease debugging

* Use binary version for SPIR-V 1.4 specific features

* Switch checks based on the SPIR-V version from the target environment
to instead use the version from the binary
* Moved header parsing into the ValidationState_t constructor (where
version based features are set)
* Added new versions of tests that assemble a 1.3 binary and validate a
1.4 environment

* Fix test for update to SPIR-V 1.4 headers

* Fix formatting

* Ext inst lookup: Add Vulkan 1.1 env with SPIR-V 1.4

* Update spirv-val help

* Operand version checks should use module version

Use the module version instead of the target environment version.

* Fix comment about two-access form of OpCopyMemory

  allowed.

than the number of total members of struct.

Move the registration of decorations. (#1895)
We currently register decorations in the first pass through the
instructions.  This is a problem because the validator has not even
checked if the decoration instructions are valid yet.  This can lead to
unexpected behaviour from these side table.  For example, in
https://github.com/KhronosGroup/SPIRV-Tools/issues/1882, we use 5GB of
data to store 1 decoration for ids that are not even defined.

Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/1882.
