[PATCH] D41762: [DWARF] Incorrect prologue end line record.

> In the case of 'shrink-wrapped code', the check is valid, as instructions before the frame setup will have correspondence to user code, hence accurate line records will be emitted.

This explanation does not validate against my mental model of shrink-wrapping. It's possible that my mental model is incorrect, but my understanding is that shrink-wrapping defers the frame setup until the first instruction that needs access to something in the frame. But that does not imply that there is no correspondence to user code before the frame setup is complete.
