spirv-fuzz: Fix problem with instruction context (#4394)
Adds an additional validity check to ensure that every instruction's
context pointer matches the enclosing IR context. Avoids a redundant
copy constructor call in TransformationDuplicateRegionWithSelection
that was leading to a bad IR context for some instructions.

Related: #4387, #4388.
Fixes #4393.

spirv-fuzz: Fix vector wrapping fuzzer pass (#4392)
The fuzzer pass was passing the type of a scalar where a vector type
was required, and was not checking whether synonyms could be made for
the operands to the scalar instruction.

spirv-fuzz: Tighten checks on null and undef pointers (#4367)
Adaps the transformations that add OpConstantUndef and OpConstantNull
to a module so that pointer undefs are not allowed, and null pointers
are only allowed if suitable capabilities are present.

Fixes #4357.

spirv-fuzz: TransformationWrapVectorSynonym that rewrites scalar operations using vectors (#4376)
Adds a new transformation that rewrites a scalar operation (like
OpFAdd, opISub) as an equivalent vector operation, adding a synonym
between the scalar result and an appropriate component of the vector
result.

Fixes #4195.

spirv-fuzz: Support atomic operations opcode (#4348)
This change captures the fact that the signedness of memory semantics

spirv-fuzz: Don't replace memory semantics / scope operands (#4349)
This change is responsible for avoiding the replacement of constant
operands with another one not constant, in the context of atomic
operations.  The related rule from the SPIR-V spec is: "All used for
Scope and Memory Semantics in shader capability must be of an
OpConstant."

Fixes #4346.

Fix BUILD.gn (#4378)
This change restricts BUILD.gn so that spirv-fuzz-related targets
are only built when in a Chromium checkout. This is due to their
dependence on protobuf, which is available in gn-friendly form in
Chromium only.

spirv-reduce: Allow merging unreachable blocks (#4303)

Add IsReachable function to IRContext (#4323)
There was a lot of code in the codebase that would get the dominator
analysis for a function and then use it to check whether a block is
reachable. In the fuzzer, a utility method had been introduced to make
this more concise, but it was not being used consistently.

This change moves the utility method to IRContext, so that it can be
used throughout the codebase, and refactors all existing checks for
block reachability to use the utility method.

Initial support for SPV_KHR_integer_dot_product (#4327)
* Initial support for SPV_KHR_integer_dot_product

- Adds new operand types for packed-vector-format
- Moves ray tracing enums to the end

- PackedVectorFormat is a new optional operand type, so it requires
  special handling in grammar table generation.

- Add SPV_KHR_integer_dot_product to optimizer whitelists.

- Pass-through validation: valid cases pass validation
  Validation errors are not checked.

- Update SPIRV-Headers
