Fix endianness of string literals (#4622)
* Fix endianness of string literals

To get correct and consistent encoding and decoding of string literals
on big-endian platforms, use spvtools::utils::MakeString and MakeVector
(or wrapper functions) consistently for handling string literals.

- add variant of MakeVector that encodes a string literal into an
  existing vector of words
- add variants of MakeString
- add a wrapper spvDecodeLiteralStringOperand in source/
- fix wrapper Operand::AsString to use MakeString (source/opt)
- remove Operand::AsCString as broken and unused
- add a variant of GetOperandAs for string literals (source/val)
... and apply those wrappers throughout the code.

Fixes  #149

* Extend round trip test for StringLiterals to flip word order

In the encoding/decoding roundtrip tests for string literals, include
a case that flips byte order in words after encoding and then checks for
successful decoding. That is, on a little-endian host flip to big-endian
byte order and then decode, and vice versa.

* BinaryParseTest.InstructionWithStringOperand: also flip byte order

Test binary parsing of string operands both with the host's and with the
reversed byte order.

* 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

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

* 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.

* Recursively checks subtypes
* new tests

* Add SPIR-V 1.4 tests for NoSignedWrap, NoUnsignedWrap

* 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

* Validate the id bound.

Validates that the id bound for the module is not larger than the max id

the validation run done by the optimizer.

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.

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.
