Ask, regardless of compatibility issues, is it possible to replace all MMX and X87 instructions with SSE3 instructions?

impossible
SSE3 just adds some instructions, which is not complete by itself
SSE2 can basically replace MMX,
There is no substitute for those trigonometric functions and logarithms in the x87 instruction
