callers changed.  Use it to handle dynamic address relocation.
	(hpread_build_psymtabs): Adjust texthigh as we read each function
	debug symbol.  Fix computation of texthigh.
	(hpread_read_subrange_type): Work around macro bugs in HP's
	compilers.
	(hpread_process_one_debug_symbol): Correctly map source lines.
