Summary: This fixes a bug introduced in D62648, where Clang could infinite loop if it became stuck on a single TypoCorrection when it was supposed to be testing ambiguous corrections. Although not a common case, it could happen if there are multiple possible corrections with the same edit distance. The fix is simply to wipe the TypoExpr from the `TransformCache` so that the call to `TransformTypoExpr` doesn't use the `CachedEntry`.
