re PR middle-end/31127 (ICE in cse_find_path, at cse.c:5930)

gcc/ChangeLog:
PR middle-end/31127
* cse.c (cse_find_path): Do not bail out if a basic block that
we already visited now becomes part of a path that starts at a
different basic block.  Just disallow this, to make sure we
visit each basic block at most once.
gcc/testsuite/ChangeLog:
PR middle-end/31127
* gcc.dg/pr31127.c: New.
