||Replace DW_FORM_strp_sup with strp_sup4 and strp_sup8
Section Many, pg Many
DW_FORM_strp_sup represents an offset within the supplementary file.
However, being a reference, the size of strp_sup depends on the DWARF-32/64 format
of the section from which the reference is made, and it should depend on the format
of the section to which the reference is made. This is the same argument for why
we have DW_FORM_ref_sup[4,8] instead of simply DW_FORM_ref_sup.
