  Reland "[flang][OpenMP] Fix lowering of LINEAR iteration variables (#188851)" (#194623)

Linear iteration variables were being treated as private. This fixes
one of the issues reported in #170784.

The regressions in the OpenMP V&V and Fujitsu testsuites happened
because the users iterator was apparently becoming invalid, after one of
its uses was replaced. This was fixed by making a copy of the list of
users.
