Make WTF::negate work correctly when negating non-negative integers
https://bugs.webkit.org/show_bug.cgi?id=273048
rdar://problem/126872453
Reviewed by Yusuke Suzuki and Keith Miller.
WTF::negate statically accepts signed integers, but ASSERTs that its input is
already negative so it can return a non-negative result. This is pretty
surprising
behavior, and since the operation of WTF::negate is a simple two's-complement
negate, it should be fine to allow it to return negative results as well.
