Makefile.in (OBJS): Add gimple-ssa-isolate-paths.o
* Makefile.in (OBJS): Add gimple-ssa-isolate-paths.o
* common.opt (-fisolate-erroneous-paths): Add option and
documentation.
* gimple-ssa-isolate-paths.c: New file.
* gimple.c (check_loadstore): New function.
(infer_nonnull_range): Moved into gimple.c from tree-vrp.c
Verify OP is in the argument list and the argument corresponding
to OP is a pointer type. Use operand_equal_p rather than
pointer equality when testing if OP is on the nonnull list.
Use check_loadstore rather than count_ptr_derefs. Handle
GIMPLE_RETURN statements.
