fix crash while checking misra_9 when initializing a union with {{0,0}} (#5250)
This fixes a crash with following error:
```
Traceback (most recent call last):

    child = self.root.getChildByValueElement(self.ed)
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'getChildByValueElement'
```

A minimal example and testcase is added. 
The extra check for nextChild seems to fix it, however i did not read
the whole codebase, so maybe this creates other issues.

Fix #11877 FP misra 10.4 On array member comparison (#5342)
I also changed the comment header to run tests on misra-test-avr8.c
because I thought that was the intention to use it like misra-test.c; if
not, I can revert.

MISRA: Speed up analysis of .ctu_info files (#4666)
* Speed up analyses of .ctu_info files
Use temporary dictionaries to eliminate duplicate typedefs,
tags and macros

* Consistency: use a cache key variable
Ensures that the get and add use the same key.

* CTU perf: use dict for macros, tags & types.
