NumTypos guard value ~0U doesn't prevent from creating new delayed
typos. When you create new delayed typos during typo correction, value
~0U wraps around to 0. This state is inconsistent and depending on total
number of typos you can hit the assertion
> Assertion failed: (DelayedTypos.empty() && "Uncorrected typos!"), function ~Sema, file clang/lib/Sema/Sema.cpp, line 366.
or have infinite typo correction loop.
Fix by disabling typo correction during performing typo correcting
transform. It disables the feature of having typo corrections on top of
other typo corrections because that feature is unreliable.
