; 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.
