        src/tests/kernel: t_signal_and_sp.c
        src/tests/kernel/arch/hppa: contextspfunc.S
        src/tests/kernel/arch/x86_64: threadspfunc.S

Log Message:
t_signal_and_sp: Fix threadsp test to actually test the thread sp.

Copypasta error had it testing alignment of signalsp instead, and
since it was always null, that always passed.  Mark it xfail on mips
now as originally expected.

While here, deal with some other issues:

- Test was failing on riscv for me because I haven't updated this
  `current' VM in a while so it didn't have the fix for 57721
  (pthread_attr_setstack incorrectly adjusts address as if for guard
  page).  Don't mark it xfail.

- Fix amd64 threadspfunc.S to adjust rsp like in all the other amd64
  stubs so it's congruent to 0 mod 16, not congruent to 8 mod 16.

- Fix hppa contextspfunc.S to use separate registers for separate
  purposes at the same time, instead of expecting addil to preserve
  %r1 AND yield a result we use later in %r1.
