Just from my point of view I love to be able to use the same command 
line for opt and bugpoint. If opt fails with a bug I just replace "opt" 
with "bugpoint" in the command line.
As I sometimes use the -std-compile-opts flag, it would be inconvenient 
to have to replace it manually. Maybe there is an easy way to get the 
-std-compile-opts support back without having to link to all those other 
libraries?

By the way, bugpoint always gives me an error if I leave the "-o" option 
in the command line. It would be nice if it could just ignore it with a 
warning. Like this I really just need to replace "opt" with "bugpoint".

Thanks for you ongoing great work on bugpoint.
