Fix uninitvar false positive in designed initializers (#5079)
Stop interpreting struct fields in designed initializers as usage of local
variables which can happen if they share the same name.

```
$ cat test.c
struct a { int b; };
int main() {
  char *b;
  extern int foo(struct a *);
  return foo(&(struct a){.b = 0});
}
$ cppcheck --quiet test.c
test.c:5:27: error: Uninitialized variable: b [legacyUninitvar]
  return foo(&(struct a){.b = 0});
```

fix skipping of cpp attributes. (#4971)
* fix skipping of cpp attributes.

* fix simplifyCPPAttribute loop.

When the first token was the start of a c++ attribute on a function,
so that tok->previous() was nullptr at the bottom of the loop,
an extra token would be skipped.  This could result in the corresponding
function being omitted from the symbol table.

* fix alignas test failure, enhance cpp attr test.

* uncrustify.

* fix redundantNextPrevious

* delete redundant code.

* add some tokenizer tests for simplifyCPPAttribute.

* enhance noreturn symbol test.

The order of a noreturn attribute and another attribute used to
matter.  Test both orders.
