spirv-fuzz: better computation of data synonym facts (#3010)
When a data synonym fact about two composites is added, data synonym
facts between all sub-components of the composites are also added.

Furthermore, when data synonym facts been all sub-components of two
composites are known, a data synonym fact relating the two composites
is added. Identification of this case is done in a lazy manner, when
questions about data synonym facts are asked.

The change introduces helper methods to get the size of an array type
and the number of elements of a struct type, and fixes
TransformationCompositeExtract to invalidate analyses appropriately.

spirv-fuzz: make equivalence classes deterministic (#3011)
An equivalence relation is computed by traversing the tree of values
rooted at the class's representative. Children were represented by
unordered sets, meaning that the order of values in an equivalence
class could be nondeterministic. This change makes things
deterministic by representing children using a vector.

The path compression optimization employed in the implementation of
the underlying union-find data structure has the potential to change
the order in which elements appear in an equivalence class by changing
the structure of the tree, so the guarantee of determinism is limited
to being a deterministic function of the manner in which the
equivalence relation is updated and inspected.

spirv-fuzz: improvements to representation of data synonym facts (#3006)
This change fixes a bug in EquivalenceRelation, changes the interface
of EquivalenceRelation to avoid exposing (potentially
nondeterministic) unordered sets, and changes the interface of
FactManager to allow querying data synonyms directly. These interface
changes have required a lot of corresponding changes to client code
and tests.

5ea7099374 Add two new simplifications. (#2984)
Implements the following simplifications:

(a - b) + b => a
(a * b) + (a * c) => a * (b + c)

Also adds logic to simplification to handle rules that create new operations
that might need simplification, such as the second rule above.

Only perform the second simplification if the multiplies have the add as their
only use. Otherwise this is a deoptimization of size and performance.

spirv-fuzz: Transformation to extract from a composite object (#2991)
At present, TransformationReplaceIdWithSynonym both extracts elements
from composite objects and replaces uses of ids with synonyms.  This
new TransformationCompositeExtract class will allow that
transformation to be broken into smaller transformations.

spirv-fuzz: rename class, and fix bug related to dominance (#2990)
Class TransformationConstructComposite has been renamed to
TransformationCompositeConstruct, to correspond to the name of the
SPIR-V instruction (as is done with e.g. TransformationCopyObject).
Running tests revealed an issue related to checking dominance in
TransformationReplaceIdWithSynonym, which is also fixed here.

spirv-fuzz: Rework management of data synonyms (#2989)
This change uses the recently-added equivalence relation class to
re-work the way synonyms between data values are managed by the fact
manager.

The tests for 'transformation_replace_id_with_synonym' have been
temporarily removed.  This is because those tests are going to be
split into a number of test classes in an upcoming PR, once some other
refactorings have been applied, and it would be burdensome to
temporarily refactor all the tests to be in a working state for this
intermediate change.

spirv-fuzz: add class to represent equivalence relation (#2988)
Adds a templated class for representing an equivalence relation on a

equal values.

Keep NOPs when comparing with original binary (#2931)
We have a check that ensures that the optimizer did not change the
binary when it says that it did not.  However, when the binary is
converted back to a binary, we made a decision to remove OpNop
instructions.  This means that any spv file that contains a NOP
originally will fail this check.

To get around this, we convert the module to a second binary that keeps
the OpNop instructions.  That binary is compared against the original.

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.

previous design which used a base and offset.

spirv-fuzz: add transformation and pass to construct composites (#2941)
Adds a fuzzer pass and transformation to create a composite (array,
matrix, struct or vector) from available constituent components, and
inform the fact manager that each component of the new composite is
synonymous with the id that was used to construct it. This allows the
"replace id with synonym" pass to then replace uses of said ids with
uses of elements extracted from the composite.

Fixes #2858.
