The caller of try_shrink_wrapping wants to be returned a single edge to
put the prologue on. To make that work even if there are multiple edges
(all pointing to the PRO block) that need the prologue, add a new block
that becomes the destination of all such edges, and then jumps to PRO.
In the general case, some edges to PRO will need to be redirected, and
not all edges *can* be redirected. This adds a can_get_prologue function
that detects such cases. This then happily can also handle the "prologue
clobbers some reg that is live on the edge we want to insert it on" case.
Not all EDGE_CROSSING edges can be redirected, so handle those the same
as EDGE_COMPLEX edges.

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.)
