  1. make panictry! private to libsyntax 

    This commit completely removes usage of the `panictry!` macro from
outside libsyntax. The macro causes parse errors to be fatal, so using
it in libsyntax_ext caused parse failures *within* a syntax extension to
be fatal, which is probably not intended.

Furthermore, this commit adds spans to diagnostics emitted by empty
extensions if they were missing, à la rust-lang#56491.
