x86, asm: Merge cmpxchg_486_u64() and cmpxchg8b_emu()
We have two functions for doing exactly the same thing -- emulating
cmpxchg8b on 486 and older hardware -- with different calling
conventions, and yet doing the same thing. Drop the C version and use
the assembly version, via alternatives, for both the local and
non-local versions of cmpxchg8b.
