Reset *THIS_CACHE in frame_unwind_try_unwinder in case of exception
It is required that unwinder->sniffer should set *this_cache to NULL if
the unwinder is not applicable or exception is thrown, so
78ac5f831692f70b841044961069e50d4ba6a76f adds clear_pointer_cleanup to set
*this_cache to NULL in case of exception in order to fix PR 14100.
https://sourceware.org/ml/gdb-patches/2012-08/msg00075.html
This patch removes that clear_pointer_cleanup, and catch all exception in
the caller of unwinder->sniffer. In case of exception, reset *this_case.
