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 5119ae84b8Fix #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.
