optimize IV -> UV conversions

This commit replaces all instances of code that looks like this:

  uv = (iv == IV_MIN) ? (UV)iv : (UV)(-iv)

with simpler and more optimal:

While -iv indeed results in an undefined behaviour when iv == IV_MIN,
-(UV)iv is perfectly well defined and does the right thing.

C standard guarantees that the result of (UV)iv (for negative iv) is
equal to iv + UV_MAX + 1 (see 6.3.1.3, paragraph 2 in C11). It also
guarantees that the result of -uv is UV_MAX - uv + 1 (6.2.5,
paragraph 9).

That means that the result of -(UV)iv is UV_MAX - (iv + UV_MAX + 1) + 1
which is equal to -iv for *all* possible negative values of iv.
