Fix segfault in SpirvTools::Disassemble when printing (#4833)
When the `SPV_BINARY_TO_TEXT_OPTION_PRINT` option is specified, `spvtext` will not be created (see 37d2396cab/source/disassemble.cpp (L117)), and the attempt to dereference into its members (`spvtext->str` and `spvtext->length`) results in segmentation fault.

This is fixed by first checking if `spvtext` is nulll.

Remove WebGPU support (#4108)
Leaves SPV_ENV_WEBGPU_0 enum in place, but marked deprecated, so users
of the library are not broken by an API enum being removed.

Fixes #4101

Add SpirvTools::IsValid(). (#2326)
* Add SpirvTools::IsValid().

Add a method to determine if a SpirvTools object was successfully
constructed and can be used.  It might not be depending on the parameter
to the constructor.
This is something a fuzzer wants to know before trying to use an
SpirvTools object constructed with a fuzzed parameter.

Add option for the max id bound. (#1870)
* Create a new entry point for the optimizer

Creates a new struct to hold the options for the optimizer, and creates
an entry point that take the optimizer options as a parameter.

The old entry point that takes validator options are now deprecated.
The validator options will be one of the optimizer options.

Part of the optimizer options will also be the upper bound on the id bound.

* Add a command line option to set the max value for the id bound.  The default is 0x3FFFFF.

* Modify `TakeNextIdBound` to return 0 when the limit is reached.

Validate the input to Optimizer::Run (#1799)
* Run the validator in the optimization fuzzers.

The optimizers assumes that the input to the optimizer is valid.  Since
the fuzzers do not check that the input is valid before passing the
spir-v to the optimizer, we are getting a few errors.

The solution is to run the validator in the optimizer to validate the
input.

For the legalization passes, we need to add an extra option to the
validator to accept certain types of variable pointers, even if the
capability is not given.  At the same time, we changed the option
"--legalize-hlsl" to relax the validator in the same way instead of
turning it off.

Cleanup includes. (#1795)
This Cl cleans up the include paths to be relative to the top level
directory. Various include-what-you-use fixes have been added.

7183ad526e Linker code cleanups
Turn `Linker::Link()` into free functions

  As very little information was kept in the Linker class, we can get rid
  of the whole class and have the `Link()` as free functions instead; the
  environment target as well as the consumer are passed along through an
  `spv_context` object.
  The resulting linked_binary is passed as a pointer rather than a
  reference to follow the Google C++ Style guidelines.

  Addresses remaining comments from
  https://github.com/KhronosGroup/SPIRV-Tools/pull/693 about the SPIR-V
  linker.

Fix variable naming in the linker

  Some of the variables were using mixed case, which did not follow the
  Google C++ Style guidelines.

Linker: Use EXPECT_EQ when possible and update some test

* Replace occurrences of ASSERT_EQ by EXPECT_EQ when possible;
* Reformulated some of the error messages;
* Added the symbol name in the error message when there is a type or
  decoration mismatch between the imported and exported declarations.

Opt: List all duplicates removed by RemoveDuplicatePass in the header

Opt: Make the const version of GetLabelInst() return a pointer

  For consistency with the non-const version, as well as other similar
  functions.

Opt: Rename function_end to EndInst()

  As pointed out by dneto0 the previous name was quite confusing and could
  be mistaken with a function returning an end iterator.
  Also change the return type of the const version to a pointer rather
  than a reference, for consistency.

Opt: Add performance comment to RemoveDuplicateTypes and decorations

  This comment was requested during the review of
  https://github.com/KhronosGroup/SPIRV-Tools/pull/693.

Opt: Add comments and fix variable naming in RemoveDuplicatePass

* Add missing comments to private functions;
* Rename variables that were using mixed case;
* Add TODO for moving AreTypesEqual out.

Linker: Remove commented out code and add TODOs

Linker: Merged together strings that were too much splitted
