Aaron Ballman 9eef4d1c5f Remove delayed typo expressions (#143423)
This removes the delayed typo correction functionality from Clang
(regular typo correction still remains) due to fragility of the
solution.

An RFC was posted here:
https://discourse.llvm.org/t/rfc-removing-support-for-delayed-typo-correction/86631
and while that RFC was asking for folks to consider stepping up to be
maintainers, and we did have a few new contributors show some interest,
experiments show that it's likely worth it to remove this functionality
entirely and focus efforts on improving regular typo correction.

This removal fixes ~20 open issues (quite possibly more), improves
compile time performance by roughly .3-.4%
(https://llvm-compile-time-tracker.com/?config=Overview&stat=instructions%3Au&remote=AaronBallman&sortBy=date),
and does not appear to regress diagnostic behavior in a way we wouldn't
find acceptable.
