Auto merge of #50838 - alexcrichton:token-impls, r=eddyb
rustc: Fix joint-ness of stringified token-streams This commit fixes `StringReader`'s parsing of tokens which have been stringified through procedural macros. Whether or not a token tree is joint is defined by span information, but when working with procedural macros these spans are often dummy and/or overridden which means that they end up considering all operators joint if they can! The fix here is to track the raw source span as opposed to the overridden span. With this information we can more accurately classify `Punct` structs as either joint or not. Closes #50700
