  [Flang][OpenMP] Fix crash when loop index var is pointer or allocatable (#129717)

Use hlfir dereferencing for pointers and allocatables and use hlfir
assign. Also, change the code updating IV in lastprivate.

Note: This is a small change. Modifications in existing tests are
changes from fir.store to hlfir.assign.

Fixes #121290
