LoongArch: Fix selector error in lasx_xvexth_h/w/d* patterns
The xvexth related instructions operate SEPARATELY according to
the high and low 128 bits, and sign/zero extend the upper half
of every 128 bits in src to the corresponding 128 bits in dest.
For xvexth.d.w, the rule for the first element of dest should be:
dest.D[0] = sign_extend (src.W[2] ,64);
instead of:
dest.D[0] = sign_extend (src.W[4] ,64);
gcc/ChangeLog:
* config/loongarch/lasx.md: Fix selector index.
