Compile aom_clear_system_state to nothing on x86 builds

As all MMX codes in libaom are now followed by an emms instruction,
there should be no need for aom_clear_system_state anymore.

To make sure that there is no missing case, this commit experimentally
compiles aom_clear_system_state away. If nothing breaks,
aom_clear_system_state can be removed from the codebase later.
