+ ; The intrinsic lowering pass was lowering intrinsics like llvm.memcpy to 
+ ; explicitly specified prototypes, inserting a new function if the old one
+ ; didn't exist.  This caused there to be two external memcpy functions in 
+ ; this testcase for example, which caused the CBE to mangle one, screwing
+ ; everything up.  :(  Test that this does not happen anymore.
