Fix out-of-bounds read in SourcePositionToScriptPosition with --hydrogen-track-positions.

Fix out-of-bounds read in SourcePositionToScriptPosition with --hydrogen-track-positions.

We were indexing into the list of inlined functions with inlining ID, which is incorrect.

There can be multiple inlinining IDs corresponding to the same inlined function, because inlining ID is inlining path sensitive unique id for an inlining attempt.

Additionally allow HAbnormalExit to have unknown source position even if we are tracking source positions. No code is generated from abnormal exits anyways.
