Handle FPs: mutexes being locked at different scopes

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.

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.

Fix #9635 (FP: Memory leak with comma operator in if-statement)
...
When checking for comparisons in if-statements, if there are comma
operators in the if-statement, skip until after the last comma.

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.

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.
