    * config/i386/i386.c (ix86_decompose_address): Use REG_P instead of
    ix86_address_subreg_operand.  Move subreg checks to
    ix86_validate_address_register.  Move address override check to
    ix86_legitimate_address_p.
    (ix86_validate_address_register): New function.
    (ix86_legitimate_address_p): Call ix86_validate_address_register
    to validate base and index registers.  Add address override check
    from ix86_decompose_address.
    (ix86_decompose_address): Remove.
