Daniel Marjamäki 04e9c13bc6 TemplateSimplifier; Better handling of c++17 fold expressions and c++20 concepts. 
c++17 fold expressions are simplified to a __cppcheck_uninstantiated_fold__ if they are not instantiated.

c++20 concepts are skipped/removed by Cppcheck and these will be enforced by the compiler.

fix daca2 gdcm template simplifier crash (#3221) 
This only fixes the crash. The templates that are instantiated are
correct but one template is left uninstantiated. Fixing the missing
instantiation is not easy and will be looked at later.

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.

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.

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 daca insighttoolkit crash in template simplifier (#2826) 
Don't count deleted instantiations in the recursive count.
I can't reduce the daca code because creduce requires a preprocessed
file to reduce and the problem doesn't show up when the file is
preprocessed with cppcheck.
There is no test because I couldn't reduce the problem files.

IOBYTE 4e222afa2c template simplifier: ignore alias template definitions with syntax errors (#2169) 
Is not allowed to define a type in an alias template definition.

This code:

template<int N>
using A1 = struct B1 { static auto constexpr value = N; };
A1<0> a1;

produces this output:

2: } ;
3: struct B1 { static const auto value = 0 a1 ;

test.cpp:2:57: error: Analysis failed. If the code is valid then please
report this failure. [cppcheckError]
using A1 = struct B1 { static auto constexpr value = N; };
                                                        ^

because it tries to instantiate the invalid alias template definition
and generates garbage code.
