Improve handling of realloc in memory leak checker ( #3036 )
...
Mark realloced variables as realloced instead of freed. This allows
improved checking for code with error realloc handling.
If cppcheck finds an if-statement which checks the validity of the
allocated memory or resource, check if the memory/resource is
reallocated from another variable. If so, we can add checking of that
variable in the if-statement instead. This allows to check that variable
for memleaks and double frees.
This fixes #9292 and #9990 which both concern FPs with double frees
after correct error handling.

remove cleanupAfterSimplify from the template simplifier ( #2998 )
...
The template simplifier works well enough now so cleanupAfterSimplify is
no longer necessary. In fact cleanupAfterSimplify was introducing a bug
which improperly simplified C++ style casts.
Bugs should be exposed and fixed properly rather than just hiding them.
