[ARM] Allow any register for DImode values in Thumb2

Ramana commented in the submission email:

    I noticed that for T32 we don't allow any old register for DImode
    values. The restriction of an even register is true only for ARM state
    because the ISA doesn't allow any old register in this place. In a few
    large .i files that I had knocking about, noticed a nice drop in stack

Add DW_AT_const_value as unsigned or int depending on type and value used.

As the comment in the code already indicated DWARF2 does provide
DW_FORM_sdata/DW_FORM_udata to represent signed/unsigned data.
Enumeration constants wider than HOST_WIDE_INT are already handled
separately. Those constant values that do fit a HOST_WIDE_INT can
be encoded as signed or unsigned depending on type and value for
more efficient encoding.
