[Bug target/37878] [4.4 regression] PPC64 ldu command generated with invalid offset

Also, note the problem is a DFmode value in a GPR.  FPRs can handle the
non-word-aligned offset.  Forcing all DFmode to be 64 bit aligned is not an
option because that is known to impose a severe performance penalty.  For
non-update form, we have handled this in rs6000_legitimize_reload_address.
