[LV] Properly extend versioned constant strides.
...
We only version unknown strides to 1. If the original type is i1, then
the sign of the extension matters. Properly extend the stride value
before replacing it.
Fixes https://github.com/llvm/llvm-project/issues/91369 .

[VPlan] Also propagate versioned strides to users via sext/zext.
...
The versioned value may not be used in the loop directly but through a
sext/zext. Add new live-ins in those cases.

[LV] Add tests showing missed propgation of versiond stride values.
...
Strides are used through a sext/zext and the known constant value (1)
isn't propagated during codegen.
