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.

5a48c0da15 SPIRV-Tools support for SPIR-V 1.5 (#2865)
* Ensure same enum values have consistent extension lists

* val: fix checking of capabilities

The operand for an OpCapability should only be
checked for the extension or core version.
The InstructionPass registers a capability, and all its implied
sub-capabilities before actually checking the operand to an
OpCapability.

* Add basic support for SPIR-V 1.5

- Adds SPV_ENV_UNIVERSAL_1_5
- Command line tools default to spv1.5 environment
- SPIR-V 1.5 incorporates several extensions.  Now the disassembler
  prefers outputing the non-EXT or non-KHR names.  This requires
  updates to many tests, to make strings match again.
- Command line tests: Expect SPIR-V 1.5 by default

* Test validation of SPIR-V 1.5 incorporated extensions

Starting with 1.5, incorporated features no longer require
the associated OpExtension instruction.

Don't register duplicate decoration in validator. (#2841)
As far as I know, it is legal to have multiple decoration adding the
same decoration to the same id.  The validator registers all of these
decoration as if they were distinct decorations.  This can cause poor
memory usage and performance in some cases.

This fix is to make sure that duplicates are not registers.

I keep the type of the decoration list as an std::vector because I
expect it to be small enough in most cases that the linear search will
still be faster that using some type of map.

No tests are added because we do not have a mechanism to test memory
usage in our unit tests.

Fixes #2837.  The total memory usage drop to 14,236KB.

11516c0b9a Validate storage class OpenCL environment rules for atomics (#2750)
This change refactors all storage class validation for atomics
to reflect the similar refactoring in the specification.

It is currently not possible to write a test for the check
rejecting Generic in an OpenCL 1.2 environment as the required
GenericPointer capability isn't allowed there. I've decided
to keep the check nonetheless to guard against the capability
becoming available without the rules for atomics being updated.

The ID changes in existing tests aren't ideal but introducing
names drags in a substantial refactoring of this file.

Contributes to #2595.

Make pointers to isomorphic type interchangeable with option. (#2570)
* Make pointers to logically matching types interchangeable with option.

DXC will be generating code where the function parameters will be a more
generic type that the actual parameter.  They should be logically
matching and the decorations of the actual parameter must be a superset
of the decorations of the formal parameter.

We want to accept this code with an options so that spirv-opt can then
inline and fix the type mismatch.  We will accept this under a new
options `--before-hlsl-legalization`.

The new option will also imply `relax-logical-pointer` so that HLSL
frontends will need to use just the one more generic option.

Moved the |LogicallyMatches| to the validation state to make it
available in more places.  Also added a parameter to have it check the
decorations.  I did not do a separate function for the decorations
because checking the decorations involves making sure the types
logically match anyway.

Convert sampled consumers to being Instructions instead of IDs (#2464)
Changing the stored value for a sampled image consumer to be the
instruction instead of result ID, since not all instructions have
result IDs. Using result IDs led to a potential crash when using
OpReturnValue, which doesn't have a result ID. OpReturnValue is not a
legal consumer, but the validator needs to look at the instruction to
determine this, thus storing the pointer to the instruction, instead
of trying to fetch the pointer using the instruction.

Issue #1528 covers fixing the check.

Remove the static maps from CheckDecorationsCompatibility (#2327)
* Remove the static maps from CheckDecorationsCompatibility

There are a few data structures in the function
`CheckDecorationsCompatibility` that are allocated using `new` and their
address is stored in a static pointer.  This code pattern causes the
MSVC memory leak checker to say there is a memory leak.  Some people
are interested in keeping that clean.

To work around it, I have replaced them with either a function or an
array of POD types.  The array can be kept as a static directly because
it has a trivial destructor, and we don't have to worry about it being
destroyed too early.
