[PATCH 2/4] Add Visium support to libgcc

Apart from the obvious historical reason, probably not, but recently added 
ports (Blackfin, Epiphany) also use it so I'm not sure we want to change it.

Files whose copyright/origin is clear are already GPL+exception, but these 6 
files were originally imported from Glibc so they aren't in the same basket.

I guess I can reuse the copyright notice of soft-fp for them.
