Ken-Patrick Lehrmann 61ccf888b3 Fix some false positives when the same expression at different places does not have the same value
Typically with
```
int F(int *f);
void F2(int *a, int *b) {
  int c = *a;
  F(a); // modifies *a
  if (b && c != *a) {}
}
```
we would get the following FP:
```
[test.cpp:3] -> [test.cpp:5]: (style) The comparison 'c != *a' is always false because 'c' and '*a' represent the same value.\n
```

I guess it boils down to isSameExpression only checking that the
expression is the same (in the above case, "*a" and "*a" are indeed the
same), but there's not real check on the values.
So the patch here is a bit hackish, and we still have false negatives in
cases with dereferenced pointers.

Rikard Falkeborn d8e7e9176b Fix FN with known condition and sizeof
cppcheck behaved differently if sizeof was to the left or right of the
comparison. In order to fix this, we cannot break the while loop until
all operands have been processed.

Rikard Falkeborn 4996ec190e Fix #9652 (fp memleak with function call with cast)
When the first argument was (void *)(1), at the start of the second
iteration, arg was pointing to the "1", which caused problems for
nextArgument(), which saw the ")" as the next token and returned
nullptr, signalling that there are no more arguments.

Instead, save the first token in the argument, which makes
nextArgument() do the right thing.

Rikard Falkeborn d5345052ab Fix #9793 (false positive, memleak with lambda)
Skip scopes with lambdas (similar to how checkleakautovar does). In
order to fix this when the lambda is inside a for loop, make
hasInlineOrLambdaFunction() recursive. This should be what all existing
users want.
