As a followon to CL 152537, modify the panic-printing traceback to also handle mid-stack inlining correctly. Also declare -fm functions (aka method functions) as wrappers, so that they get elided during traceback. This fixes part 2 of #26839. Fixes #28640 Fixes #24488 Update #26839 Change-Id: I1c535a9b87a9a1ea699621be1e6526877b696c21 Reviewed-on: https://go-review.googlesource.com/c/153477 Reviewed-by: David Chase <drchase@google.com>
