x86: checkasm: check for or handle missing cleanup after MMX instructions
Not every asm routine is expected clear the MMX state after returning.
It is however a requisite for testing floating point code in checkasm.
Annotate functions requiring cleanup with declare_func_emms() and issue
emms after the call. The remaining functions are checked for having a
cleared MMX state after return.
