2019-07-23Rollup merge of #62851 - matklad:unescape, r=petrochenkovMark Rousskov-609/+5
move unescape module to rustc_lexer It makes sense to keep the definition of escape sequences closer to the lexer itself, and it is also a bit of code that I would like to share with rust-analyzer. r? @petrochenkov

2019-07-20Introduce rustc_lexerAleksey Kladov-1247/+531
The idea here is to make a reusable library out of the existing rust-lexer, by separating out pure lexing and rustc-specific concerns, like spans, error reporting an interning. So, rustc_lexer operates directly on `&str`, produces simple tokens which are a pair of type-tag and a bit of original text, and does not report errors, instead storing them as flags on the token.

2019-07-15Rollup merge of #62668 - goodmanjonathan:fix-62660, r=estebankMark Rousskov-1/+1
Fix #62660 If the explicitly given type of a `self` parameter fails to parse correctly, we need to propagate the error rather than dropping it and causing an ICE. Fixes #62660.
