Prefer libproc_macro APIs to libsyntax ones in the quasi-quoter. The shift to using `proc_macro`'s own APIs in `proc_macro::quote`, both in the implementation of the quasi-quoter and the Rust code it generates to build `TokenStream`s at runtime, greatly reduces the dependency on `libsyntax`, with the generated runtime code being completely free of it. This is a prerequirement for introducing more abstraction/indirection between `proc_macro` and compiler implementation details (mainly those from `libsyntax`), which I want to attempt. cc @alexcrichton @jseyfried @nrc
