Summary: The `FN_loop2` was not actually FN because infer analyzes its complexity as degree 1 correctly.

Summary:
In the previous report, it reported the first cost of node that exceeds a threshold. However, this
may hide a bigger cost of node that appears later. This diff changes this to report the biggest
cost of node among the costs exceeding the threshold.

It returns non-top value when one of the parameters of band is positive, i.e., `x & 255` returns
`[0, 255]` instead of top.

Summary:
This diff avoids giving the top value to unknown globals in Java,
because they harm precision of the cost checker. Instead, it doesn't
subst the global symbols at function calls.

avoid FPs from parser code.

Summary:
Since it does not make sense to get ranges of non-integer values and
use them as approximate iteration numbers, this diff ignores control
values that only contain non-integer symbols.
