SPARC: Fatal_halt use source and exit codes
The Fatal_halt handler now have two options, either halt
as before or enter system error state to return to
debugger or simulator. The exit-code is now also
propagated to the debugger which is very useful for
testing.
The CPU_Fatal_halt handler was split up into two, since
the only the LEON3 support the CPU power down.
The LEON3 halt now uses the power-down instruction to save
CPU power. This doesn't stop a potential watch-dog timer
from expiring.
