Revert using ? for try! in the libsyntax pretty printer

Browse Source

The use of ...?instead of try!(...) in libsyntax makes
extracting libsyntax into syntex quite painful since it's
not stable yet. This makes backports take a much longer time
and causes a lot of problems for the syntex dependencies. Even
if it was, it'd take a few release cycles until syntex would
be able to use it. Since it's not stable and that this feature
is just syntax sugar, it would be most helpful if we could remove
it.
