that an id is always considered irrelevant if it comes from a dead block.

Fixes #3733.

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: Transformation to replace the use of an irrelevant id (#3697)
A transformation that replaces the use of an irrelevant id with
another id of the same type.

The related fuzzer pass, for every use of an irrelevant id,
checks whether the id can be replaced in that use by another
id of the same type and randomly decides whether to replace
it.

Fixes #3503.
