Fix two bugs in __cxa_end_cleanup() Per the EHABI32 specification, __cxa_end_cleanup must take care to preserve registers before calling _Unwind_Resume(). So, libcxxrt uses an assembly stub which preserves caller-saved registers around the call to __cxa_get_cleanup(). But: - it failed to restore them properly, - it did not preserve the link register. Fix both of these problems. This is needed to fix exception unwinding on FreeBSD with LLVM 14. Note that r4 is callee-saved but is pushed onto the stack to preserve stack pointer alignment.
