Preserve more registers in sigcontext, and restore them in sigreturn. This

makes the sigreturn regress test pass, as well as todd@'s ``run
sh -c "trap exit 2 3;while :; do sleep 120; done", then press ^C'' test pass.

Since userland setjmp uses sigcontext, the kernel will still support the
old layout for a while (until libc is fixed and a reasonable grace period
is over).
