I'm not sure about 32-bit targets, I'd expect that it would be mostly
fine assumption, but it would contradict efforts to support crts from
win9x era. For 64-bit it's always available, SSE is a requirement
there, we should be able to just skip runtime check there.
A random document on the Internet suggests that Windows 98 has partial
support for SSE (without unmasked exceptions) in the appendix. This
document claims itself as authored by Intel which I can't verify:

I was mostly thinking about win9x era hardware, not the OS itself, but I
don't really know how our support for win9x is used.
