Change the syscall invocation sequences to no longer fetch the last few
arguments from the stack, since the kernel will now copyin() them when
necessary.
This makes all system calls (but mmap()) slightly faster.
WARNING! After this commit, your binaries must run against a kernel
featuring m88k/m88k/trap.c r1.34 or better - i.e. a 4.1 or later kernel.
