So that we get to cancel away the allocation for the lazily used base.

We can move `powImpl` (which *is* strict in the base) to the top-level
so that we don't duplicate too much code and move the SPECIALISATION
pragmas onto `powImpl`.

The net effect of this change is that `(^)` plays along much better with
inlining thresholds and loopification (#22227), for example in `x2n1`.

Fixes #22324.
