  undefined behaviour

spirv-fuzz: Locate instructions more efficiently (#4189)
Avoids redundantly searching the whome module when locating an
instruction from its descriptor - instead, only the block containing
the instruction needs to be searched.

spirv-fuzz: simplify transformation for replacing an id with a synonym (#3020)
Prior to this change, TransformationReplaceIdWithSynonym was designed
to be able to replace an id with some synonymous data descriptor,
possibly necessitating extracting from a composite into a fresh id in
order to get at the synonymous data.  This change simplifies things so
that TransformationReplaceIdWithSynonym just allows one id to be
replaced by another id.  It is the responsibility of the associated
fuzzer pass - FuzzerPassApplyIdSynonyms - to perform the extraction
operations, using e.g. TransformationCompositeExtract.

spirv-fuzz: fuzzer pass to adjust memory access operands (#2968)
A new pass that gives spirv-fuzz the ability to adjust the memory
operand masks associated with memory access instructions (such as
OpLoad and OpCopy Memory).

Fixes #2940.

spirv-fuzz: Rework id descriptors (#2959)
A refactoring that separates the identification of an instruction from
the identification of a use in an instruction, to enable the former to
be used independently of the latter.
