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.
