  [SystemZ][z/OS] Fix the entry point marker for leaf functions

The function emitFunctionEntryLabel does not look at whether or not a function is a leaf when setting the entry flags,
and instead blindly marks all functions as non-leaf routines. Change it to check if a function is a leaf function and
mark it accordingly.
