- now we detect int / bool / char ...
- fixed this case:

```c
int v = 0;
// as int was not a recognized type, this was resulting in an empty expr
```

- fixed cc dump of argument
- now we store a range of position
note: we can't just use a range because we may do later on macro expansion in it:

```c
test b;

// ---- error

2  |  test b;
    |  ^^^ in expansion of macro test
    |     |
1  |  #define test (void* aaaa)
    |                                        ^^^^ invalid identifier in type
```
- used because global variable are handled differently than local variable
+ added sema_scope _reset
+ added pass in sema
+ remove visit_statement
+ format code
- use a simpler structure
- reformat code
- removed CREF macro
+ put scan_srcref_info in it
- also moved cc error dumping in the parse error handling translation unit
- simplified code of error dumping (even if it is still a little bit cursed)
- renamed struct of srcref to make simpler to understad what is a characted index and what is a line index
