  On e.g. gcc211 the use of "%li" with unsigned HOST_WIDE_INT led to this warning:
../../src/gcc/analyzer/access-diagram.cc: In member function ‘void ana::string_literal_spatial_item::add_column_for_byte(text_art::table&, const ana::bit_to_table_map&, text_art::style_manager&, ana::byte_offset_t, ana::byte_offset_t, int, int) const’:
../../src/gcc/analyzer/access-diagram.cc:1909:40: warning: format ‘%li’ expects argument of type ‘long int’, but argument 3 has type ‘long long unsigned int’ [-Wformat=]
          byte_idx_within_string.ulow ()));
and to all values being erroneously printed as "0".

Fixed thusly.

Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.
Verified that this fixes the analyzer.exp=out-of-bounds-diagram*.c tests
on gcc211 (sparc-sun-solaris2.11).
Pushed to trunk as r14-9199-g939439a90f234f.

	PR analyzer/110483
	PR analyzer/111802
	* access-diagram.cc
	(string_literal_spatial_item::add_column_for_byte): Use %wu for
	printing unsigned HOST_WIDE_INT.
