sparc64 update.
- Prototype userspace layer implementation that
at least relates to sparc64 and compiles cleanly.
- Fixes for kernel's preemptible_handler and code
related to running userspace.
- Enable userspace. Several dozen instructions
are now run in userspace! We are pretty near
the userspace milestone for sparc64. |

Fix interrupt handlers to save global registers. |

Context again. It turns out, according to SCD 2.4, that registers that didn't have to be saved were saved (%o1 - %o5) and
registers that had to be saved were not saved (%i0 - %i5, %l0 - %l7). |

The context_save/context_restore needed two other improvements.
First, storing of %fp because of window_fills.
Second, flushing all active windows before CONTEXT_LOAD to make CWP - 1 the overlap window. |
