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

Remove use of deprecated googletest macro (#2286)
* Remove use of deprecated googletest macro

INSTANTIATE_TEST_CASE_P has been deprecated.  We need to use
INSTANTIATE_TEST_SUITE_P instead.

* Remove extra commas from test suites.

Change handling of unknown extentions in validtor. (#1951)
This commit will change the message for unknown extensions from an error
to a warning.

Code was added to limit the number of warning messages so that consummer
of the messages are not overwhelmed.  This is standard practice in
compilers.

Many other issues were found at while looking into this. They have been
documented in #1950.

Fixes http://crbug.com/875547.

Cleanup includes. (#1795)
This Cl cleans up the include paths to be relative to the top level
directory. Various include-what-you-use fixes have been added.

Remove using std::<foo> statements. (#1756)
Many of the files have using std::<foo> statements in them, but then the
use of <foo> will be inconsistently std::<foo> or <foo> scattered
through the file. This CL removes all of the using statements and
updates the code to have the required std:: prefix.

082b8b08f1 More automatic extension support
Update grammar table generation:
- Get extensions from instructions, not just operand-kinds
- Don't explicitly list extensions that come from the SPIR-V core
  grammar or from a KHR extended instruction set grammar.

This makes it easier to support new extensions since the recommended
extension strategy is to add instructions to the core grammar file.

Also, test the validator has trivial support for passing through
the extensions SPV_NV_shader_subgroup_partitioned and
SPV_EXT_descriptor_indexing.

43ca2112b8 Stop asking for extensions if feature avaiable in core SPIR-V
Migrating to unified grammar means we sometimes have two fields
for a certain feature: version and extensions. It means the feature
in question can be used either in SPIR-V of advanced-enough
versions or in any SPIR-V with with the specified extensions.

Validator now respects the above rules.

3c2e4c7d99 Fix validation of group ops in SPV_AMD_shader_ballot
This needs custom code since the rules from the extension
are not encoded in the grammar.

Changes are:
- The new group instructions don't require Group capability
  when the extension is declared.
- The Reduce, InclusiveScan, ExclusiveScan normally require the Kernel
  capability, but don't when the extension is declared.

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.

0d3b8329a4 Make enums for all currently published extensions
Use the list from the SPIR-V registry page.  Also, capture it as
a string so it's much easier to update via copy-paste.

The validator will accept modules that declare these known
extensions.  However, we might not know about new tokens or
instructions declared in them.  For that we need grammar updates
applied to SPIRV-Headers.

7fe8a57a5b Support SPV_AMD_gcn_shader
Supported in assembler, disassembler, and binary parser.

The validator does not check SPV_AMD_gcn_shader validation rules
beyond parsing the extension.

Adds generic support for generating instruction tables for vendor
extensions.

Adds generic support for extensions the validator should recognize
(but not check) but which aren't derived from the SPIR-V core
grammar file.

c804c125c5 Autogenererating enum-string mappings from grammar
Autogenerating the following code:
- extension enum
- extension-to-string
- string-to-extension
- capability-to-string

Capability mapping table will not compile if incomplete.
TODO: Use "spirv-latest-version.h" instead of 1.1.

Added function to generate capability tables for tests.

1c43cb8550 Validator parses and registers OpExtension
Known extensions are saved in validation state. Unknown extension
produce a dignostic message, but do not fail the validation.

Moved extension definitions to their own file.
