[LLVMdev] Accessing/Loading a new pass

[Ben Chambers]

Ah, I was missing that include/llvm/LinkAllPasses.h change.  Thanks!
Now I have it working, except for the fact that it doesn't seem to
generate fresh names for things.  Or if it does, they're the empty
string (I suspect it is the latter, since when I create the new
instruction the empty string is passed in for the name of the
instruction).  Is there some way to get a new name (like tmp155) and
have a high degree of confidence that it is actually unique?
