runtime: use inlined function name for traceback elision Currently, gentraceback decides which frames to print or elide when unwinding inlined frames using only the name of the outermost function. If the outermost function should be elided, then inlined functions will also be elided, even if they shouldn't be. This happens in practice in at least one situation. As of CL 258938, exported Go functions (and functions they call) can now be inlined into the generated _cgoexp_HASH_FN function. The runtime elides _cgoexp_HASH_FN from tracebacks because it doesn't contain a ".". Because of this bug, it also elides anything that was inlined into it. This CL fixes this by synthesizing a funcInfo for the inlined functions to pass to showframe. Fixes #42754.
