Patch is to improve debugging.

I probably commit it after the issue is closed.  Arguments against
the commit is that the change imposes small performance penalty
due to save and restore of the %ebp (I doubt that this is measureable
by any means).  Also, arguably, such change should be done for all
functions in support.s, but bcopy() is the hot spot.
