This was my first attempt. Two problems. 1) Above API was meant for  
'used' attribute on decls.  and
asserts any any other kind of declarations. 2) I did not want to  
misuse LLVMUsed for anything
other than what it was originally intended for. This is in case, other  
clients want to preserve
this distinction. Change looks like a lot, but it is pretty simple.
