[Bug middle-end/39157] Code that compiles fine in 1GB of memory with 4.1.2 requires > 20GB in 4.2.* and higher

Actually for PR26854 it is just one loop that is detected, covering all of
the function (with approx. 56000 basic blocks and one basic-block that has
edges to all other basic blocks in the loop).  So the default for the param
could indeed be 10000 here.  And possibly it's not really the large number
of blocks but that the in/out-degree of that single basic-block with the
computed goto.

Thus, I'd suggest again to not recognize such loops or maybe mark them
specially?
