Bug 1548908: Add InfinityBits to FloatingPoint.h r=jwalden
...
We can't generate a constexpr uint64_t containing the bits for positive/negative infinity, because of a (very sensible) static_assert in SpecificNaNBits. This patch adds support to FloatingPoint.h for infinity. The next patch will use it to make JS::InfinityValue constexpr (to match JS::NaNValue).
