[SystemZ] Remove the ManipulatesSP flag from backend (NFC).
This flag was set in the presence of stacksave/stackrestore in order to force
a frame pointer.
This should however not be needed per the comment in MachineFrameInfo.h
stating that a a variable sized object "...is the sole condition which
prevents frame pointer elimination", and experiments have also shown that
there seems to be no effect whatsoever on code generation with ManipulatesSP.
