re PR middle-end/87099 (internal compiler error: segmentation fault)

PR middle-end/87099
* calls.c (maybe_warn_nonstring_arg): Punt early if
warn_stringop_overflow is zero.  Don't call get_range_strlen
on 3rd argument, keep iterating until lenrng[1] is INTEGER_CST.
Swap comparison operands to have constants on rhs.  Only use
lenrng[1] if non-NULL and INTEGER_CST.  Don't uselessly
increment lenrng[0].

* gcc.dg/pr87099.c: New test.
