Only return the function token from checkTokenInsideExpression when it
might be one the argument (hence keeping a pointer to one of them).
Otherwise, we can directly skip to the token after the function call.

Improve isSameExpression for literals (#2514)
Improve isSameExpression() for literals with same value but different
representation, for example  the following different ways of
representing 9 as double: 9.0, 0.9e1 and 0x1.2p3.

With this change, cppcheck can (for example) correctly detect that the
else if statements are always false in the following example:

	void f(double x) {
		if (x < 9.0) {}
		else if (x < 0x1.2p3) {}
		else if (x < 0.9e1) {}
	}

Rikard Falkeborn 0bb98aeef9 Fix 9577 (endless recursion in Valueflow::bifurcate()) (#2492)
Ensure bifurcate() does not recurse endlessly where a variable is
initialized recursively, or a variable is initialized as x(0) or x{0}
followed by a recursive assignment (for example int x(0); x = x / 1;).

The first case is solved by bailing out if there initialization is done
using x(0) or x{0}, the second by adding a missing depth argument to a
recursive call.

Ken-Patrick Lehrmann 5f73e1cb32 Fix 9546: properly check that the bound is the size (#2475)
Previously, as the check was done on the token and not on the ast,
`i <= v.size()` and `i <= v.size() - 2` would both raise the same
warning.

This patch fixes this, but this mean the check is only done when the
condition if `i <= v.size()`. Any other (more complex) condition is
ignore, and so we have false negative for instance with
 `i <= v.size() + 1`.

Ken-Patrick Lehrmann eca7ee9260 9356: Prevent false positive when passing non-const reference to member constructor (#2370)
* Add cases for 9356

* 9356: Prevent false positive when passing non-const reference to member constructor

This workarounds false positives 'Parameter  can be declared with const [constParameter]'
when said parameter is used in constructor call. It assume the
constructor call might change the parameter (without any checks.
The drawback is that we have false negative, in cases where we could
check the constructor actually takes a const reference, or a copied by
value parameter.
