Summary WTF::FloatHash is invalid for 0 / -0

Because FloatHash does a bitwise hash, 0 and -0 get different hash values, even though they compare equal. That's a hash table no-no. More info here: http://virtualdub.org/blog/pivot/entry.php?id=259. Simplest solution is to mask the sign bit when computing a FloatHash. Another option is to treat -0 as a special case, and return the hash value for 0.
