[Bug libc/1468] New: AMD64 {get,set,swap,make}context use wrong offsets into ucontext_t


The offsets into ucontext_t for fpregs, sigmask, fpregsmem, and mxcsr (as
specified in sysdeps/unix/sysv/linux/x86_64/ucontext_i.h) are wrong.

Fixing this could be a potential ABI change, although I don't see how anything
that ever used these fields could have possibly worked in the first place.
