Looks like a regression from clang-15: https://cpp1.godbolt.org/z/7Tz75G7Mo |

…nside a constraint scope We preserve the trailing requires-expression during the lambda expression transformation. In order to get those referenced parameters inside a requires-expression properly resolved to the instantiated decls, we intended to inject these 'original' ParmVarDecls to the current instantiaion scope, at `Sema::SetupConstraintScope`. The previous approach seems to overlook nested instantiation chains, leading to the crash within a nested lambda followed by a requires clause. This fixes llvm#73418.
