spirv-val: Consistently quote ids in messages (#4950)
Half the messages used to output 'id[%name]' and half id[%name].  With
this change, all messages consistently output 'id[%name]'.  Some typos
are also fixed in the process.

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

[val] Fixup id name output (#2158)
This CL changes the id/name output from the validator to always use a
consistent id[%name] style. This removes the need for getIdOrName. The
name lookup is changed to use the NameMapper so the output is consistent
with what the disassembler will produce.

Fixes #2137

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

Validate all type ids. (#1868)
* Validate all type ids.

The validator does not check if the type of an instruction is actually
a type unless the OpCode has a specific requirement.  For example,
OpFAdd is checked, but OpUndef is not.

The commit add a generic check that if there is a type id then the id
defines a type.

http://crbug.com/876694

* Merge other checks for type into new one.

There are a couple check that the type id is a type for specific
opcodes.  Those have been mereged into 1.

Small changes to other test cases to make them valid enough for the
purpose of the test.
