Emilio Cobos Álvarez 0b9fa22976 Bug 1701942 - Use bitwise equality for font variation value comparisons. r=jfkthame 
Just like we do for font sizes / size-adjust in gfxFontStyle.

Chris Peterson 7bc752e42b Bug 1571631 - Replace MOZ_MUST_USE with [[nodiscard]] in mfbt. r=sg 
Also move MOZ_MUST_USE before function declarations' specifiers and return type. While clang and gcc's __attribute__((warn_unused_result)) can appear before, between, or after function specifiers and return types, the [[nodiscard]] attribute must precede the function specifiers.

Depends on D108344

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).
