-fsanitize=function emits a signature and function hash before a function. Similar to 7f6e2c9, these can be sheared off when `.subsections_via_symbols` is used. This change uses the same technique 7f6e2c9 introduced for prefixes: emitting a symbol for the metadata, then marking the actual function entry as an .alt_entry symbol.
