Which Firefox platforms must support x86 without SSE2? Just Win32 and Linux?

SSE2 is not just about SIMD. The most important thing it buys us IMHO is to
be able to not use x87 instructions anymore and instead use SSE2 (scalar)
instructions. That removes entire classes of bugs caused by x87 being
non-IEEE754-compliant with its crazy 80-bit registers.

What does requiring SSE2 buy us? 1% of hundreds of millions of Firefox
users is still millions of people.
