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) {}
	}
