--- We map STG registers onto appropriate CmmExprs.  Either they map
--- to real machine registers or stored as offsets from BaseReg.  Given
--- a GlobalReg, get_GlobalReg_reg_or_addr produces either the real
--- register it is in, on this platform, or a CmmExpr denoting the
--- address in the register table holding it.
