Denys Vlasenko f92ae1dc4b tls: P256: change logic so that we don't need double-wide vectors everywhere 
Change sp_256to512z_mont_{mul,sqr}_8 to not require/zero upper 256 bits.
There is only one place where we actually used that (and that's why there
used to be zeroing memset of top half!). Fix up that place.
As a bonus, 256x256->512 multiply no longer needs to care for
"r overlaps a or b" case.

This shrinks sp_point structure as well, not just temporaries.
