dwarf2out.c (multiple_reg_loc_descriptor): Use dbx_reg_number for spanning registers. 

2013-05-21  Christian Bruel  <christian.bruel@st.com>

        * dwarf2out.c (multiple_reg_loc_descriptor): Use dbx_reg_number for
        spanning registers. LEAF_REG_REMAP is supported only for contiguous
        registers. Set register size out of the PARALLEL loop.
