perf probe: Fix to walk all inline instances

Fix line-range collector to walk all instances of inlined function,
because some execution paths can be optimized out depending on the
function argument of instances.

E.g.)
inline_func (arg) {
if (arg)
do_something;
else
do_another;
}

func_A() {
inline_func(1)
}

func_B() {
inline_func(0)
}

In this case, func_A may have only do_something code and func_B may have
only do_another.
