Iain Ireland 00ae116a04 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).

Nicholas Nethercote 2511b2c327 Bug 1267550 (part 2) - Rename MOZ_WARN_UNUSED_RESULT as MOZ_MUST_USE. r=froydnj.
It's an annotation that is used a lot, and should be used even more, so a
shorter name is better.
