    [PR99378] LRA: Skip decomposing address for asm insn operand with unkno=
wn
constraint.

      Function get_constraint_type returns CT__UNKNOWN for empty constraint
    and CT_FIXED_FORM for "X".  So process_address_1 skipped
    decompose_mem_address only for "X" constraint.  To do the same for empty
    constraint, skip decompose_mem_address for CT__UNKNOWN.
