spirv-reduce: Eliminate skeletal structured control flow construct (#4360)
This change allows spriv-reduce to get rid of a selection, switch or
loop construct if none of the instructions defined in the construct
are used outside the construct.

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.

spirv-reduce: Cleanup a few things (#4352)
Cleans up a CMakeLists.txt file and the header guard for a reduction
opportunity, and gets rid of an unnecessary parent function field that
can be derived from an existing block field.

Invalidate analyses (#4260)
Some reduction opportunities don't invalidate all analyses. This PR
fixes the situation (although we might invalidate more analyses than
required).

CMake: Add SPIRV_TOOLS_BUILD_STATIC flag (#3910)
If enabled the following targets will be created:

* `${SPIRV_TOOLS}-static` - `STATIC` library. Has full public symbol visibility.
* `${SPIRV_TOOLS}-shared` - `SHARED` library. Has default-hidden symbol visibility.
* `${SPIRV_TOOLS}`        - will alias to one of above, based on BUILD_SHARED_LIBS.

If disabled the following targets will be created:

* `${SPIRV_TOOLS}`        - either `STATIC` or `SHARED` based on the new `SPIRV_TOOLS_LIBRARY_TYPE` flag. Has full public symbol visibility.
* `${SPIRV_TOOLS}-shared` - `SHARED` library. Has default-hidden symbol visibility.

Defaults to `ON`, matching existing build behavior.

This flag can be used by package maintainers to ensure that all libraries are built as shared objects.

spirv-reduce: Support reducing a specific function (#3774)
Motivated by integrating spirv-reduce into spirv-fuzz, so that an
added function can be made smaller during shrinking, this adds support
in spirv-reduce for asking reduction to be restricted to the
instructions of a single specified function.

spirv-reduce: Refactoring (#3793)
Avoids the use of "using" in favour of explicit qualification, to be
consistent with spirv-fuzz. Fixes indentation in a TODO comment.
Addresses and removes two existing TODO comments by moving some helper
functionality into reduction_util.

Related issue: #2184.

'sanity' and 'sanity check' were previously used.

CMake: Enable building with BUILD_SHARED_LIBS=1 (#3490)
Rename the `${SPIRV_TOOLS}` target to `${SPIRV_TOOLS}-static` and alias `${SPIRV_TOOLS}` to either `${SPIRV_TOOLS}-static` or `${SPIRV_TOOLS}-shared` depending on `BUILD_SHARED_LIBS`.

Re-point all internal uses of `${SPIRV_TOOLS}` to `${SPIRV_TOOLS}-static`.

`${SPIRV_TOOLS}-static` is explicitly renamed to just `${SPIRV_TOOLS}` to ensure the name does not change from current behavior.

Build the `SPIRV-Tools-*` libraries as static, as this is what they always were.

Force the external targets `gmock` and `effcee` to be built statically. These either do not support being built as shared libraries, or require special flags.

Issue: #3482

spirv-reduce: Remove unused uniforms and similar (#3321)

used by decorations with which they are intimately connected, such as
descriptor set and binding decorations.

9c0ae6bb8e Improved CMake install step. (#2963)
Added exports for libraries. External libraries that themselves use
libraries require all dependencies have exports, so not having exports can
cause major problems when used within other projects.

Install paths for exports are now placed in the proper directories expected
by Windows and *nix systems. Config files are generated as well, which
should work with CMake's find_package() function once installed.

reduce: improve remove unref instr pass (#2945)
* Remove Impl struct in Reducer; we can re-add it later (in a cleaner fashion) if we need to. 
* Add cleanup passes in Reducer; needed so that removal of constants can be disabled during the main passes, and then enabled during cleanup passes, otherwise some main passes can perform worse due to lack of available constants. 
* Delete passes: remove op name, remove relaxed precision. And delete associated tests. 
* Add more tests for remove unreferenced instructions. 
* Always return and write the output file, even if there was a reduction failure. 
* Only exit with 0 if the reduction completed or we hit the reduction step limit.

Extend reducer to remove relaxed precision decorations (#2797)
Adds a reduction pass that removes OpDecorate and OpMemberDecorate
instructions that annotate instructions and members with
RelaxedPrecision.  As well as being useful in its own right, removing
such references allows other passes to remove further instructions.

Implement WebGPU->Vulkan initializer conversion for 'Function' variables (#2513)
WebGPU requires certain variables to be initialized, whereas there are
known issues with using initializers in Vulkan. This PR is the first
of three implementing a pass to decompose initialized variables into
a variable declaration followed by a store. This has been broken up
into multiple PRs, because there 3 distinct cases that need to be
handled, which require separate implementations.

This first PR implements the basic infrastructure that is needed, and
handling of Function storage class variables. Private and Output will
be handled in future PRs.

This is part of resolving #2388

reduce: Add two branch reduction passes (#2507)

* Fix #2501. `simple_conditional_branch_to_branch` reduction pass changes "simple" conditional branches to branches. 
* Fix #2503. `conditional_branch_to_simple_conditional_branch` proper handling of back-edges.

Improve reducer algorithm and other changes (#2472)
Fix #2475. Fix #2476. 

* Improve reducer algorithm: shrink granularity, remove an early return, no lazy initialization, notify pass if binary is interesting, add comments.
* Add fail-on-validation-error option to fail a reduction if an invalid state is reached; useful for tests.
* Set fail-on-validation-error in tests.
* Improve some documentation comments.
* Add Reducer::AddDefaultReductionPasses so tests (and other library consumers) can add the default reduction passes.
* Add CLIMessageConsumer in test_reduce so we can see messages for tricky tests.
* Remove test RemoveUnreferencedInstructionReductionPassTest_ApplyReduction because it was indirectly testing the reduction algorithm, not the RemoveUnreferencedInstruction pass.
* Tweak tests where needed.

Add some val options to reduce (#2401)
Fix #2396 

* Check that initial state is valid. Add kInitialStateInvalid. 
* Fix RemoveOpnameAndRemoveUnreferenced test; turns out the original shader is invalid, but we never notice because we don't check this and the reduced shader is valid; fix original shader. Assert reduction status is kComplete.
* Always check return value from `Reducer::Run`.
* Change Reducer::Run to *not* immediately copy the input binary.

98c67d3850 Fixed names in ifdefs and GetName functions that had been forgotten in a previous refactoring. Also shortened names of test files as those files test both the new 'finder' classes introduced in the refactoring, as well as the 'reduction pass' class; the shorter names capture both.

86d0d9be25 Refactored reducer so that the 'finding' functionality of a reduction pass are separated from the generic functionality for tracking progress of a pass. With this change, we now have a ReductionOpportunityFinder abstract class, with many subclasses for each type of reduction, and just one ReductionPass class, which has an associated finder. (#2321)
Sounds good.
