target/i386: Add ZMM_OFFSET macro

Add a convenience macro to get the address of an xmm_regs element within
CPUX86State.

This was originally going to be the basis of an implementation that broke
operations into 128 bit chunks. I scrapped that idea, so this is now a purely
cosmetic change. But I think a worthwhile one - it reduces the number of
function calls that need to be split over multiple lines.

No functional changes.
