Martin Storsjö 7ec2354c38 x86: Remove inline MMX assembly that clobbers the FPU state ... These inline implementations of AV_COPY64, AV_SWAP64 and AV_ZERO64 are known to clobber the FPU state - which has to be restored with the 'emms' instruction afterwards. This was known and signaled with the FF_COPY_SWAP_ZERO_USES_MMX define, which calling code seems to have been supposed to check, in order to call emms_c() after using them. See 0b1972d409, 29c4c0886d and df215e5758 for history on earlier fixes in the same area. However, new code can use these AV_*64() macros without knowing about the need to call emms_c(). Just get rid of these dangerous inline assembly snippets; this doesn't make any difference for 64 bit architectures anyway.
