Richard Sandiford 76f8ae87b4 [SystemZ] Define the call instructions as pseudo aliases.
Similar to r191364, but for calls.  This patch also removes the shortening
of BRASL to BRAS within a TU.  Doing that was a bit controversial internally,
since there's a strong expectation with the z assembler that WYWIWYG.
