[llvm] Expose DWARFDebugLine::LineTable::getFileNameEntry

Authored by mtrofin on Jun 12 2019, 2:27 PM.



This is useful for scenarios where Prologue was directly used and DWARF
5 awareness is required. The current alternative would be to either
duplicate the logic in getFileNameEntry, or to use getFileNameByIndex.
The latter isn't quite an in-place replacement - it performs some
processing, and it produces a string instead of a StringRef, meaning
the caller needs to handle its lifetime.
