Log:
    PR tree-optimization/64715
    * passes.def: Add another instance of pass_object_sizes before
    ccp1.
    * tree-object-size.c (pass_object_sizes::execute): In
    first_pass_instance, only handle __bos (, 1) and __bos (, 3)
    calls, and keep the call in the IL, as {MIN,MAX}_EXPR of the
    __bos result and the computed constant.  Remove redundant
    checks, obsoleted by gimple_call_builtin_p test.

    * gcc.dg/builtin-object-size-15.c: New test.
    * gcc.dg/pr64715-1.c: New test.
    * gcc.dg/pr64715-2.c: New test.
