Only pass 'returned' to target-specific lowering code when the value of entire register is guaranteed to be preserved.

Add more tests for r179925 to verify correct handling of signext/zeroext; strengthen condition check to require actual MVT::i32 virtual register types, just in case (no actual functionality change)

Extra paranoid test for r179925 (verify that tail calls are not generated to 'this'-returning constructors of objects with different 'this' pointers than the caller)

Add CodeGen support for functions that always return arguments via a new parameter attribute 'returned', which is taken advantage of in target-independent tail call opportunity detection and in ARM call lowering (when placed on an integral first parameter).
