Currently, gentraceback suppresses the "unexpected return pc" error for sigpanic's caller if the M was running C code. However, there are various situations where a sigpanic is injected into C code that can cause traceback to unwind *past* the sigpanic before realizing that it's in trouble (the traceback beyond the sigpanic will be wrong). Rather than try to fix these issues for Go 1.10, this CL simply disables complaining about unexpected return PCs if we're in cgo regardless of whether or not they're from the sigpanic frame. Go 1.9 never complained about unexpected return PCs when printing, so this is simply a step closer to the old behavior. This should fix the openbsd-386 failures on the dashboard, though this issue could affect any architecture. Fixes #23640.
