Move a variety of predicates from TargetInstrInfo into

when you don't have TII around. Now you can use MI->getDesc()->isBranch()

all of the predicates have been moved over yet.

Make DAE not wipe out attributes on calls, and not drop
...
return attributes on the floor. In the case of a call
to a varargs function where the varargs arguments are
being removed, any call attributes on those arguments
need to be dropped. I didn't do this because I plan to
make it illegal to have such attributes (see next patch).
With this change, compiling the gcc filter2 eh test at -O0
and then running opt -std-compile-opts on it results in
a correctly working program (compiling at -O1 or higher
results in the test failing due to a problem with how we
output eh info into the IR).
