Tidy tc-ppc.c XCOFF auxent access

It's better not to drill down into u.auxent but instead use a pointer
to the combined_entry_type.  That way the fix_scnlen field is
available, and no one looking at the codes needs to wonder whether
coffsymbol (symbol_get_bfdsym (sym))->native[i + 1] is the same
auxent.

	* config/tc-ppc.c (ppc_frob_symbol): Tidy XCOFF auxent access.
	(ppc_adjust_symtab): Likewise.
