aarch64: Do not force a stack frame for EH returns
EH returns no longer rely on clobbering the return address on the stack
so forcing a stack frame is not necessary.
This does not actually change the code gen for the unwinder since there
are calls before the EH return.
gcc/ChangeLog:
* config/aarch64/aarch64.cc (aarch64_needs_frame_chain): Do not
force frame chain for eh_return.
