spirv-fuzz: Avoid invalidating analyses in various transformations (#4205)
Avoids invalidating all analyses in transformations that add
constants, OpUndef and global and local variables.

spirv-fuzz: Report fresh ids in transformations (#3856)
Adds a virtual method, GetFreshIds(), to Transformation. Every
transformation uses this to indicate which ids in its protobuf message
are fresh ids. This means that when replaying a sequence of
transformations the replayer can obtain a smallest id that is not in
use by the module already and that will not be used by any
transformation by necessity. Ids greater than or equal to this id
can be used as overflow ids.

Fixes #3851.

spirv-fuzz: Pass submanagers to other submanagers when necessary (#3796)
This PR changes the fact manager so that, when calling some of the
functions in submanagers, passes references to other submanagers if
necessary (e.g. to make consistency checks).

In particular:

- DataSynonymAndIdEquationFacts is passed to the AddFactIdIsIrrelevant
  function of IrrelevantValueFacts

- IrrelevantValueFacts is passed to the AddFact functions of
  DataSynonymAndIdEquationFacts

The IRContext is also passed when necessary and the calls to the
corresponding functions in FactManager were updated to be valid and
always use an updated context.

Fixes #3550.

spirv-fuzz: Introduce TransformationContext (#3272)
Some transformations (e.g. TransformationAddFunction) rely on running
the validator to decide whether the transformation is applicable.  A
recent change allowed spirv-fuzz to take validator options, to cater
for the case where a module should be considered valid under
particular conditions.  However, validation during the checking of
transformations had no access to these validator options.

This change introduced TransformationContext, which currently consists
of a fact manager and a set of validator options, but could in the
future have other fields corresponding to other objects that it is
useful to have access to when applying transformations.  Now, instead
of checking and applying transformations in the context of a
FactManager, a TransformationContext is used.  This gives access to
the fact manager as before, and also access to the validator options
when they are needed.

spirv-fuzz: Transformations to add types, constants and variables (#3101)
This change adds several transformations that allow types, constants,
undefined values and global variables to be added to a module.
