Daniel Marjamäki 26a11e20d0 Revert "Fix crash with garbage code (#2547)"
This reverts commit b25709a492.

The real problem was wrong AST for valid code, I want to fix that instead.

9575: false positive in fclose (#2540)
Fix false positive introduced by
0b7649ca9b

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 same valued literals with followvar (#2519)
It allows (for example) cppcheck to detect that the lhs and the rhs are
the same in the following example:

	double g()
	{
        	double a = 1e1
	        return a & 10.0;
	}

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.
