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).

532 6906 d 4 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
528 6909 d 3 h jermar /kernel/trunk/ sparc64 work.
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.

Perform leaf-procedure optimization for context_save and context_restore.
 
526 6909 d 10 h jermar /kernel/trunk/ sparc64 work.
No need to save/restore local registers.
