Various minor/cosmetic improvements to code

2018-12-07T23:53:34+00:00

Split up `pretty_print` and `print`.

2018-11-29T06:14:57+00:00

`pretty_print` takes a `Token` and `match`es on it. But the particular `Token` kind is known at each call site, so this commit splits it into five functions: `pretty_print_eof`, `pretty_print_begin`, etc. This commit also does likewise with `print`, though there is one callsite for `print` where the `Token` kind isn't known, so a generic `print` has to stay (but it now just calls out to the various `print_*` functions).

Use `Cow` in `Token::String`.

`Printer::word` takes a `&str` and converts it into a `String`, which causes an allocation. But that allocation is rarely necessary, because `&str` is almost always a `&'static str` or a `String` that won't be used again. This commit changes `Token::String` so it holds a `Cow<'static, str>` instead of a `String`, which avoids a lot of allocations.

Remove `huge_word` and `zero_word`.

2018-11-29T06:12:15+00:00

They are unused. The commit also adds some blank lines between some methods.

Fix whitespace in `pp.rs`.

This commit converts some 2-space indents to 4-space indents.

Deny bare trait objects in in src/libsyntax

Extend Printer::buf on demand.

2018-04-30T09:24:24+00:00

So that 55 entries (at 48 bytes each) don't need to be eagerly initialized on creation. This speeds up numerous rust-perf benchmark runs, by up to 3%.
