Previously we would attribute some frames of inline stacks to the wrong
line number.

For inlined frames, the source position table contains the line number
of the most-inlined frame (innermost). It's quite possible that this
function is within another script though, in which case the line number
will be wrong. Fix that here by taking the script from the
InliningStack, rather than assuming it is the same script as the
original code entry.
