PATCH: add PGI (SGS Thomson) DWARF extensions to readelf

Therefore appended below is such a patch. When my copyright assignment
is all done I'll resubmit the other parts of the original patch which
actually _use_ these values. In the meantime having them in the
headers at least gives them some visibility and (I hope) prevents
other compiler writers from using the same numbers for other
extensions.
