This PR makes it so that we don't allocate lots of one-element sets just to compute which line number to scroll to, when a call node is double-clicked.

We only use the total hits anyway, to compute which line to scroll to.

I didn't add any tests for the new function; I think it is sufficiently
covered by the existing tests for getNativeSymbolsForCallNode.
And the next commit will make the address / line timings code use it,
which will contribute some more test coverage.
