Harald van Dijk 09f43ca916 Avoid some undefined behavior in test_bruteforce. (#2400) ...

* Ulp_Error*: ilogb(reference) - 1 may overflow if reference is zero.
* binary_i_double Test: DoubleFromUInt32's result is a cl_double and the
attempt is to store it as a cl_double, but p was defined as a pointer to
cl_ulong, resulting in an unintended implicit conversion that is not
valid for out-of-range doubles.
* exp2, tanpi: ensure early exit for NaN.
* shift_right_sticky_128: avoid out-of-range shift if shift value is
exactly 64.
* scalbn: e += n may overflow if n is large, move it after the check for
large n.
