This gets the new token-tree quasiquoter up to the point of being able to stand in for of
#astin the pipe protocol compiler;#astis only there in#[cfg(stage0)], whereas it'squote_expr!andquote_type!in#[cfg(stage1)]and[#cfg(stage2)]. Also makes the splicing machinery much more robust and extensible (you are allowed to splice anything that implementsToTokens).While this looks like a lot of sound and noise for nothing, it enables (post-snapshot) cutting out substantial portions of the redundant macro machinery in the frontend.
