  [clang] fix crash when evaluating __is_bitwise_cloneable on an invalid type (#183707)

fixes https://github.com/llvm/llvm-project/issues/183665

The crash was caused by `isBitwiseCloneableType` **infinitely
recursing** when a record type contains a self-referential field
produced by typo correction during error recovery (e.g. ABCD corrected
to ABC inside struct ABC).

This patch adds an early `RD->isInvalidDecl()` check to bail out before
recursing into fields and bases of invalid record declarations.
