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 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.

The template simplifier works well enough now so cleanupAfterSimplify is

which improperly simplified C++ style casts.
Bugs should be exposed and fixed properly rather than just hiding them.

fix #9983 (TemplateSimplifier: template not simplified : f(0,0);) ( #2905 )
...
Currently template type deduction for functions only works for single
template argument single function argument functions with a literal
argument.
This patch starts to add support for single template argument multiple
function argument functions. It correctly handles functions with
multiple arguments of the same type. It also handles a mix of template
and non-template arguments.
It does not add support for overloading non-template arguments.
It does not add support for multiple parameter template functions.
It does not add support for type deduction from variable arguments.

Fix #9647 : Set correct enum value ( #2856 )
...
* Tokenize: Set varId for variables in enum
Set varIds in enum values. It was previously disabled in 5119ae84b8
to avoid issues with enums named the same as global variables. Take care
to only set varids to variables used to set the value of an enumerator,
not the enumerator itself. This is somewhat complicated by the fact that
at the time this happens, astOperand1(), astOperand2(), astParent() etc
are not set. The current implementation is not perfect, for example in
the code below, y will not have a varid set, but x and z will. This is
deemed sufficient for now.
int x, y, z;
enum E { a = f(x, y, z); };
* Fix #9647 : Value of enums with variables as init values
C++ allows enum values to be set using constexprs, which cppcheck did
not handle before. To solve this, add a new pass to valueflow to update
enum values after global consts have been processed. In order to do so,
I moved all settings of enum values to valueflow. After setting the enum
values, we need another call to valueFlowNumber() to actually set users
of the enums.
There is still room for improvements, since each pass of
valueFlowGlobalConstVar() and valueFlowEnumValue() only sets variables
that are possible to set directly, and not if setting the value of a
variable allows us to set the value of another. For example
constexpr int a = 5;
constexpr int b = a + 5;
enum E { X = a };
constexpr E e = X;
Here both b and e will not have their values set, even though cppcheck
should be possible to figure out their values. That's for another PR
though.
This was tested by running test-my-pr.py with 500 packages. The only
difference was one error message in fairy-stockfish_11.1, where cppcheck
now printed the correct size of an array instead of 2147483648 which I
assume is some kind of default value. In that package, using a constexpr
when setting enum values is common, but as mentioned, there was no
change in the number of warnings.
