    hppa: Fix integer REG+D address reloads
    
    I made a mistake in the previous change to integer_store_memory_operand.
    There is no support pa_emit_move sequence to handle secondary reloads of
    integer REG+D instructions.  Further, the Q constraint is used for some
    non-simple instructions (movb and addib).  Thus, we need to return true
    when reload is in progress.

            * config/pa/predicates.md (integer_store_memory_operand): Return
            true for REG+D addresses when reload_in_progress is true.
