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

* 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

Check forward reference in OpTypeArray. (#2307)
In a recent PR, we allowed a forward reference for the element type in
an array declaration.  However, we do not have other check to make sure
the forward reference is a pointer type first reference in
OpTypeForawrdPointer.  We add that check.

Fixes https://crbug.com/920074.

Validate OpForwardPointer (#2156)
* Validate OpForwardPointer

The validator does not have a a check that OpForwardPointer is giving
a forward reference to a pointer type.  We add that check.

https://crbug.com/910852

* Remove more specialized check.

There was a check that the forward pointer is actually a poiner type,
but it was only done if it was used in a struct.  This was too specific.
Remove it in favour of the more general check that was added.

* Format

* Check the storage type in OpTypeForwardPointer

* Fix typo is test case epxected results.

[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

03cbf33a69 Validator: FPRoundingMode decoration (#1482)
This commit checks the following when Shader capability exists:
"The FPRoundingMode decoration can be applied only to a width-only
conversion instruction that is used as the Object operand of an
OpStore storing through a pointer to a 16-bit floating-point object
in the StorageBuffer, Uniform, PushConstant, Input, or Output
Storage Classes.".

Add validation check for arrays of void type. (#1880)
In the definition of an array
(https://www.khronos.org/registry/spir-v/specs/1.2/SPIRV.html#Array),
it specfically mentions that array elements have non-void type.  I've
added a check for that in this PR.

Change when instruction is registered in validator. (#1840)
When doing the validator checks, an instruction is currently registered
at the end of IdPass.  This creates an inconsistency.  In IdPass, an
instruction that uses its own result will treat that use as a forward
reference.  Then in the following passes it will not because the
definition can be found.

It seems best to update the state after all of the check have been done
for the current instruction.  This makes it consistent for all of the
passes.

This makes a different when trying to verify OpTypeStruct.

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.

Validate Ids before DataRules. (#1622)
Validate Ids before DataRules.

The DataRule validators call FindDefs with the assumption that they
definitions being looked at can be found. This may not be true if we
have not validated identifiers first.

This CL flips the IdPass and DataRulesPass to fix this issue.

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.

1c11c8690f Validation of OpEntryPoint usage.
According to the SPIRV Spec (2.16.1):
* There is at least one OpEntryPoint instruction, unless the Linkage
capability is being used.

* No function can be targeted by both an OpEntryPoint instruction and an
OpFunctionCall instruction.

Also updated unit tests to includ OpEntryPoint.

Rules of the SPIR-V Spec:

Forward reference operands in an OpTypeStruct
* must be later declared with OpTypePointer
* the type pointed to must be an OpTypeStruct
* had an earlier OpTypeForwardPointer forward reference to the same <id>

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.
