partial revert of b1eaa3021f (#3174)
It is necessary to use a fake NameAndToken in
mTypesUsedInTemplateInstantiation rather than a Token pointer so the
template simplifiers internal state is kept valid when tokens are
deleted. This prevents a use after free.

Fix tokenizing of x[i](0) (Fixes #8875) (#3167)
Fix faulty removal of parenthesis when "]" is followed by parenthesis
with a number inside, for example when calling a function pointer in
an array or (perhaps more common) in c++, calling operator ( on an
element in an array.

Fixes #8875 where such wrong simplification lead to a FP with too many
bits shifted due to "<<" was interpreted like a shift operator rather
than a stream output.

Fix #10182 (FN memory leak with if-statement) (#3151)
Improve leak detections in if-statements. This is done by checking
for leaks every time a scope is left. This allows cppcheck to catch
more memory leaks, as well as improve some error messages which now
contain the line where the variable goes out of scope, instead of the
end of the function.

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

Bugs should be exposed and fixed properly rather than just hiding them.
