autovectorization
is fine, no need to support RVV into middle-end.

From my understanding, we dont have RVV instruction for fmax/fmin?

There's things like .POPCOUNT

So for now, I don't need to support builtin call function vectorization
for RVV.

vectorization by using RVV instructions.

Thanks Jeff.
Will commit with formating the codes.
I am gonna first support COND_FMA and reduction first (which I think
is higher priority).
Then come back support strided_load/store.
Sure.One thing to note with strided loads, they can significantly

Ok for trunk?
Assuming this removes the strided loads/stores while we figure out the
best way to support them, OK for the trunk. The formatting is so messed
up
