Some guests only have, or additionally have, 64-bit vectors.
For example arm, mips, sparc.  So it's best to enable this
whenever we can.  As with tcg/i386, use 64-bit loads and stores
but 128-bit vector registers.

If LASX is available (all current loongarch64 cpus?), we have
256-bit vectors as well.  Useful for guests that support such
things, e.g. aarch64, i386, and loongarch64 itself.
