David Daney 1ef0910cfd MIPS: BPF: Quit clobbering callee saved registers in JIT code.
If bpf_needs_clear_a() returns true, only actually clear it if it is
ever used.  If it is not used, we don't save and restore it, so the
clearing has the nasty side effect of clobbering caller state.

Also, don't emit stack pointer adjustment instructions if the
adjustment amount is zero.
