b9441f2428 Improve char escaping in lexer messages 
Currently ', " and \ are escaped as \', \" and \\ respectively. This
leads to confusing messages such as `error: unknown start of token: \\`
when encountering a single backslash.

Fix by emitting printable ASCII characters directly. This will still
escape \r, \n, \t and Unicode characters.

Fixes #47902

e862695158 Auto merge of #41990 - qnighy:disallow-underscore-suffix-for-string-like-literals, r=nikomatsakis 
Disallow underscore suffix for string-like literals.

This patch turns string/bytestring/char/byte literals followed by an underscore, like `"Foo"_`, to an error.

`scan_optional_raw_name` will parse `_` as a valid raw name, but it will be rejected by the parser. I also considered just stopping parsing when the suffix is `_`, but in that case `"Foo"_` will be lexed as two valid tokens.

Fixes the latter half of #41723.

094eaf0250 Rollup merge of #37208 - jseyfried:fix_partially_consumed_tokens_in_macros, r=nrc 
macros: fix partially consumed tokens in macro matchers

Fixes #37175.

This PR also avoids re-transcribing the tokens consumed by a matcher (and cloning the `TtReader` once per matcher), which improves expansion performance of the test case from #34630 by ~8%.
