4b5ae211da Eliminate YGFloatOptional::getValue()
Summary:
@public

Replace `YGFloatOptional::getValue()` with `YGFloatOptional::unwrap()`.

`YGFloatOptional::getValue()` has the unfortunate property of calling `std::exit` if the wrapped value is undefined.

Here, we eliminate the method, and just call `.unwrap()` everywhere.

aaa018bbea Remove YGUnwrapFloatOptional
Summary:
Replaces `YGUnwrapFloatOptional` with `YGFloatOptional::unwrap`.

This leads to more idiomatic C++, and to less function call nesting, thus increasing readability.

6bdd39d0ed Store YGFloatOptional in 32 bits
Summary:
@public

After removing `-ffast-math`, `NaN` can again be used to represent `undefined`. That allows us to remove the additional flag from `YGFloatOptional`, and reduce memory usage.

50ec35575f Eliminate YGFloatOptional::getValue()
Summary:
@public

`YGFloatOptional::getValue()` has the unfortunate property of calling `std::exit` if the wrapped value is undefined.
That forces `x.isUndefined() ? fallback : x.getValue()` as access pattern.

Here, we replace that by introducing `YGFloatOptional::orElse(float)` which encapsulates that pattern. Other additions are `orElseGet([] { … })` and some extra operators.
