Florian Hahn 5c93fce720 [VPlan] Model initial header mask as region value. (#196199) ...

Introduce a new VPRegionValue for the header mask, managed by loop
regions similar to the canonical IV.

The main benefit is we do not need to materialize the mask early and it
is trivial to find (no more need for patterns hard-coded in findHeaderMask).

It is currently materialized before computing costs, as we compute costs
for part of it currently.
