2021-12-03	Auto merge of #91393 - Julian-Wollersberger:lexer_optimization, r=petrochenkov	bors	-13/+7
	Optimize `rustc_lexer` The `cursor.first()` method in `rustc_lexer` now calls the `chars.next()` method instead of `chars.nth_char(0)`. This allows LLVM to optimize the code better. The biggest win is that `eat_while()` is now fully inlined and generates better assembly. This improves the lexer's performance by 35% in a micro-benchmark I made (Lexing all 18MB of code in the compiler directory). But lexing is only a small part of the overall compilation time, so I don't know how significant it is. Big thanks to criterion and `cargo asm`.
2021-12-01	Replace `nth_char(0)` with `next()` in `cursor.first()`	Julian Wollersberger	-13/+7
	and optimize the iterator returned by `tokenize(). This improves lexer performance by 35%

2021-11-23	Tokenize emoji as if they were valid indentifiers	Esteban Kuber	-0/+25
	In the lexer, consider emojis to be valid identifiers and reject them later to avoid knock down parse errors.

2021-06-26	Reserve prefixed identifiers and string literals (RFC 3101)	lrh2000	-5/+12
	This commit denies any identifiers immediately followed by one of three tokens `"`, `'` or `#`, which is stricter than the requirements of RFC 3101 but may be necessary according to the discussion at [Zulip].

2021-04-08	Fix outdated crate names in compiler docs	pierwill	-3/+3
	Changes `librustc_X` to `rustc_X`, only in documentation comments. Plain code comments are left unchanged. Also fix incorrect file paths.
2020-12-03	Fix some clippy lints	Joshua Nelson	-5/+5

2020-10-30	Add back missing comments	Joshua Nelson	-0/+1

2020-10-30	Fix even more clippy warnings	Joshua Nelson	-6/+4

2020-10-09	Noticed a potential bug in `eat_while()`: it doesn't account for number of ↵	Julian Wollersberger	-20/+14
	UTF8 bytes. Fixed it by inlining it in the two places where the count is used and simplified the logic there.
2020-09-21	Fix typo in rustc_lexer docs	LingMan	-1/+1
	Also add an Oxford comma while we're editing that line.
2020-09-02	lexer: Tiny improvement to shebang detection	Vadim Petrochenkov	-5/+9
	Lexer now discerns between regular comments and doc comments, so use that. The change only affects the choice of reported errors.
