added pair of inputs for hypotf in binary32
This pair yields an error of 1 ulp in binary32, whereas the current
maximal known error for hypotf on x86_64 is zero:
Checking hypot with glibc-2.37
hypot 0 -1 -0x1.003222p-20,-0x1.6a2d58p-32 [0.501] 0.500001 0.500000001392678
libm gives 0x1.003224p-20
mpfr gives 0x1.003222p-20
