PeepholeOpt: Fix losing subregister indexes on full copies (#161310)
Previously if we had a subregister extract reading from a
full copy, the no-subregister incoming copy would overwrite
the DefSubReg index of the folding context.

There's one ugly rvv regression, but it's a downstream
issue of this; an unnecessary same class reg-to-reg full copy
was avoided.
