SIS MP success

[Jiri Gaisler]

After implementing the interrupt broadcast function, and stop telling
the software that there are 5 cores in the system when there really only
are 4, all tests run fine ..:-) I can run all SMP tests with a time slot
of 50 clocks except smpclock01.exe, which fails with:

*** BEGIN OF TEST SMPCLOCK 1 ***

Lowering the time slot to 15 clocks fixes this error and the test passes.

I will clean up my sources, and work a bit on improving breakpoint
handling and tracing. The MP function broke erc32 and leon2 support, so
I will fix that too. After that I can post a patch if anyone is
interested. Threaded simulation could come after that ...

Jiri.
