Mark Mentovai d98a4de718 win: support native x86 CONTEXT structures with x87 but no SSE context
When no SSE (fxsave) context is available but x87 (fsave) context is, use the
x87 context.

This also embeds the x87 FPU opcode from the fxsave fop field in bits 16-26 of
the fsave error_selector field, true to the layout of the fsave structure. See
Intel SDM volume 1 (253665-061) 8.1.10 and figure 8-9.
