[PATCH] Generic BUG for i386
This makes i386 use the generic BUG machinery. There are no functional
changes from the old i386 implementation.
The main advantage in using the generic BUG machinery for i386 is that the
inlined overhead of BUG is just the ud2a instruction; the file+line(+function)
information are no longer inlined into the instruction stream. This reduces
cache pollution, and makes disassembly work properly.
