The existing spirv-opt `DebugInfoManager::AddDebugValueForDecl()` sets
the scope and line info of the new added DebugValue using the scope and
line of DebugDeclare. This is wrong because only a single DebugDeclare
must exist under a scope while we have to add DebugValue for all the
places where the variable's value is updated. Therefore, we have to set
the scope and line of DebugValue based on the places of the variable
updates.
This bug makes
https://github.com/google/amber/blob/main/tests/cases/debugger_hlsl_shadowed_vars.amber
fail. This commit fixes the bug.
* Validate SPV_KHR_workgroup_memory_explicit_layout
* Check if SPIR-V is at least 1.4 to use the extension.
* Check if either only Workgroup Blocks or only Workgroup non-Blocks
are used.
* Check that if more than one Workgroup Block is used, variables are
decorated with Aliased.
* Check layout decorations for Workgroup Blocks.
* Implicitly use main capability if the ...8BitAccess or
...16BitAccess are used.
* Allow 8-bit and 16-bit types when ...8BitAccess and ...16BitAccess
are used respectively.
* Update SPIRV-Headers dependency
Bump it to include SPV_KHR_workgroup_memory_explicit_layout.
* Add option to validate Workgroup blocks with scalar layout
Validate the equivalent of scalarBlockLayout for Workgroup storage
class Block variables from SPV_KHR_workgroup_memory_explicit_layout.
Add option to the API and command line tool.
Propagating the OpLine/OpNoLine to preserve the debug information
through transformations results in integrity check failures because of
the extra line instructions. This commit lets spirv-opt skip the
integrity check when the code contains OpLine or OpNoLine.
When there is an array of strutured buffers, desc sroa will only split
the array, but not a struct type in the structured buffer. However,
the calcualtion of the number of binding a struct requires does not take
this into consideration. This commit will fix that.
Avoid generating OpPhi on void types, and allow the transformation to
take place on regions that produce pointer and sampled image result
ids if such ids are not used after the region.
Fixes#3787.
* validation: tighter validation of multisampled images
- if MS=1, then Sample image operand is required
- Sampling operations are not permitted when MS=1
Fixes#4057, #4058
* Fail early for multisampled image for sampling, dref, gather
* validate StorageImageMultisampled capability
The StorageImageMultisampled capability is required when declaring
an image type with with Multisampled==1 and it's a storage image (Sampled == 2)
Fixes#4061
* Allow SubpassData with Multisampled and Sampled==2
The eliminate dead member pass is written assuming that the index to an
OpAccessChain will be a 32-bit integer or 64-bit integer. That is
changed to work for any width 64-bits or less.

* Add validation for ray tracing builtins
- Remove existing InstanceId testing that was combined with VertexId in awkward ways.
- Rather than adding a new set of functions for each ray tracing builtin, add
an error table that maps the builtin ID to the 3 common VUIDs for each builtin
(I could see this being extended for other builtins in the future).
- add F32 matrix validation function
- augment existing PrimitiveId validation to verify Input storage class for the
RT stages this is accepted in, and correct the list of stages that it is actually
accepted in (only Intersection / Any Hit / Closest Hit)
* add testing for ray tracing builtins
- remove exising InstanceId testing as it was tangled in with VertexId in now weird ways
and combine it with the new tests
- add testing for ray tracing builtins
- builtins accepted in the same stages and of the same types are combined into test functions
- add some new matrix types to the code generator so they can be used for testing
This instruments ImageRead, ImageWrite and ImageFetch when applied to
texel buffers.
Also add new (but not yet generated) buffer OOB error codes differentiated
for VUID classification.
* BuildModule: optionally avoid adding new OpLine instructions
Fixes#4029 for my use case
* Fix formatting
* Create last_line_inst_ only if doing extra line tracking
* Update to final ray tracing extensions
Drop Provisional from ray tracing enums

Add terminator support for SpvOpIgnoreIntersectionKHR and SpvOpTerminateRayKHR

MeshShadingNV: enables PrimitiveId, Layer, and ViewportIndex

Fix buffer oob instrumentation for matrix refs.
Matrix stride decoration is not on matrix type but is a member decoration
on the enclosing struct type. Also correctly apply matrix stride depending
on row or column major.
spirv-opt has a bug that `DebugInfoManager::AddDebugValueWithIndex()` does not
preserve `Indexes` operands of
[DebugValue](https://www.khronos.org/registry/spir-v/specs/unified1/OpenCL.DebugInfo.100.html#DebugValue).
It has to preserve all of those `Indexes` operands, but it preserves only the first index
operand.
This PR removes `DebugInfoManager::AddDebugValueWithIndex()` and lets the spirv-opt
use `DebugInfoManager::AddDebugValueForDecl()`.
`DebugInfoManager::AddDebugValueForDecl()` preserves the Indexes operand correctly.
in 3943 the new tests should have failed, but didn't due to the AnyVUID
check not handling case with trailing whitespace. Added trimming to handle
it as easily might happen again in future
