my various SUIF/gcc related patches

[Jeffrey A Law]

Just an FYI; I've got a tree with the bytecode stuff removed.  I'll
try to get it checked in when I return to SLC later this week.

Removing the bytecode crap reduces the size of cc1's .text segment
by about 1.5%.  Not bad for 30minutes of work to remove a feature
that hasn't ever been used, is totally broken and would need a
complete and total redesign before being useful.
