std::sort JS profiling data instead of insert-sorting it
The original FunctionCall struct is much smaller than the resulting
FunctionCallProperties, and thus not as expensive to copy. Repeatedly
calling upper_bound on a QVector is not such a great idea, either.
Since the usage of QVector instead of QList for the results is new
in Qt 5.6, the insert-sorting got slower, making this change a fix
for a performance regression.
