2019-02-23	Rollup merge of #58476 - nnethercote:rm-LazyTokenStream, r=petrochenkov	Mazdak Farrokhzad	-3/+2
	Remove `LazyTokenStream`. `LazyTokenStream` was added in #40939. Perhaps it was an effective optimization then, but no longer. This PR removes it, making the code both simpler and faster. r? @alexcrichton

	Fix style nits discovered in reading code.
2019-02-18	Remove `LazyTokenStream`.	Nicholas Nethercote	-3/+2
	It's present within `Token::Interpolated` as an optimization, so that if a nonterminal is converted to a `TokenStream` multiple times, the first-computed value is saved and reused. But in practice it's not needed. `interpolated_to_tokenstream()` is a cold function: it's only called a few dozen times while compiling rustc itself, and a few hundred times across the entire `rustc-perf` suite. Furthermore, when it is called, it is almost always the first conversion, so no benefit is gained from it. So this commit removes `LazyTokenStream`, along with the now-unnecessary `Token::interpolated()`. As well as a significant simplification, the removal speeds things up slightly, mostly due to not having to `drop` the `LazyTokenStream` instances.
