Remove a debugging hack which could be used to cause the
undocumented 'icebp' instruction to enable QEMU internal
debug logging. This code has always been #ifdeffed out
since it was introduced in commit aba9d61e34b9 in 2005;
judging by the rest of that commit (which is entirely
unrelated) it may have even been committed by accident.

(Note that WANT_ICEBP is not defined by default anyway.)
