604a9a98a9 guard against INF values in CompactValue
Summary:
After this diff D13403925 that got rid of `-ffast-math` we started to have a very odd behavior on Yoga when using release builds.

After digging a while we found that certain set of conditions on O2 and O3 optimization levels was causing Origami to set some `INFINITE` values on Yoga.

We found the root of the problem and fix it on Origami side. But I'm wondering if guarding agains `INFINITE` on Yoga side would be good too. Since now Yoga it's not using `-ffast-math` anymore, and I think infinite is not a a valid value anywhere on Yoga side, it seems to support the reason to guard against it.

I'm happy to abandon this diff if you guys think this is not a good solution.

885b4cbdfb Switch storage in YGStyle to CompactValue
Summary:
@public

Switches the storage in `facebook::yoga::detail::Values` from `YGValue` to `facebook::yoga::detail::CompactValue`.
This cuts heap size for arrays of values in half.

8bc89651d6 Introduce CompactValue
Summary:
@public

`CompactValue` represents a `YGValue` in 32bits instead of 64. This comes at the cost of a range limitation, as one exponent bit is borrowed for the unit.

*Undefined* and *Auto* have no magnitude, and are represented as *NaN* values.

The data structure is meant to be used as a field type on `YGStyle` to save memory.

This is header-only for efficient inlining.
