There are some old dependency versions in rustc-ap-syntax, rustc-ap-syntax_pos. Should I update them as well?

[Xanewok]

These are autopublished from the rustc code so we need to first update the actual libsyntax{,_pos} here in-tree and then when that change propagates to crates.io we can bump those in a lockstep (together with tools) later on.
