Fix math.frexp() and add more tests (thanks Florob, Link Mauve, xnyhps)

local m, e = math.frexp(1);
assert(m == 0.5 and e == 1, "frexp(1)");

local m, e = math.frexp(0);
assert(m == 0 and e == 0, "frexp(0)");

local m, e = math.frexp(3);
assert(m == 0.75 and e == 2, "frexp(3)");

local m, e = math.frexp(-1);
assert(m == -0.5 and e == 1, "frexp(-1)");

local m, e = math.frexp(0.5);
assert(m == 0.5 and e == 0, "frexp(0.5)");

local m, e = math.frexp(0.1);
assert(m == 0.8 and e == -3, "frexp(0.1)");
