spirv-fuzz: Optimize transformations ( #4216 )
...
Avoids blanket invalidation of analyses in several transformations,
instead updating the def-use manager and instruction to block mapping.

spirv-fuzz: Improve transformation test oracles ( #4207 )
...
To help ensure that optimizations that do less cautious invalidation
of analyses are implemented correctly, this change adds checks to the
tests of various transformations to ensure that analyses such as
def-use are up to date.

spirv-fuzz: Fix bug related to transformation applicability ( #3990 )
...
This PR fixes a bug related to the transformation applicability.
When the OpNot case was implemented, its opcode was not
added to the list of supported bit instructions in IsApplicable.
So, the changes made are the following.
- Add OpNot to the list of supported bit instructions.
- Update the tests.
