On s390{,x}, r2 is scrambled after syscall entry
This was caught by system_call_params.exp test case:
exe->mount("source", "target", "filesystemtype", 0, nil <unfinished ...>
mount@SYS("", "target", "filesystemtype", 0, nil) = -2
<... mount resumed> = -1
Note how the first parameter disappears--r2 now holds syscall number
(21 in this case), and the original value is stored in orig_gpr2 in
save area.
