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.

Ken-Patrick Lehrmann 5c1a2db434 Fix handling of c++ casts in template expansion
Cast were not expanded properly: the `<` was not taken into account in
typeindentlevel, so we would then miss a `>`, resulting in syntaxError.

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.
