Use a consistent argument order in TargetLoweringObjectFile.

Use a consistent argument order in TargetLoweringObjectFile.

These methods normally call each other and it is really annoying if the
arguments are in different order. The more common rule was that the arguments
specific to call are first (GV, Encoding, Suffix) and the auxiliary objects
(Mang, TM) come after. This patch changes the exceptions.
