linemap_position_for_loc_and_offset() tries to generate a location_t
encoding a column offset from the current location, for example, point
to a certain character inside a string. This is trivial to do when the
new location "fits within" the map of the original location. However,
it may happen that the (long) line corresponding to the original
location is encoded in several maps, thus the new location should
actually be encoded in a subsequent map from the original location.
This patch detects this case and adjusts the map correspondingly.
(This shows that the line-map representation is quite wasteful in this
case, because line-maps always start at column 0. That is, map[0]
highest location may encode up to line 8 column 80, then
map[1]->start_location starts encoding at line 8 column 0. Thus, there
are two location_t values that point to the same source location.)

In do_warn_aggressive_loop_optimizations, we convert to a tree just to print a
widest_int. Apart from overly complicated, this results in printing '3u'
instead of just '3'.
Unfortunately, adding a printf-like conversion specifier would require making
pretty-print.c link with wide-int.cc, which will include a lot of new
dependencies into several other programs (gcov-tool for example). It would be
possible to add the conversion specifier to every FE pretty-printer, but this
still would require updating c-format.c, which is far from trivial. A simpler
approach is to convert to a string rather than to a tree.
In addition, "iteration 3 invokes undefined behavior within this loop" seems to
me clearer than "iteration 3 invokes undefined behavior; containing loop".
