Hi @jeanPerier and @tarunprabhu,

     Sorry for the long absence on this PR. I had internal reprioritisation, on which I needed to focus for the past several months.

     I have reworked this PR. To recall, the previous version of the PR was emitting parser nodes (AssignmentStmt node in particular) during lowering, which thereafter invoked `evaluateAssignment` to assign uninitialised local variables to 0 in the presence of the `-finit-local-zero` flag. The current (reworked) implementation uses hlfir assign instead.

    Going forward, I would be able to provide quick turnaround on any comments you may have. Thanks for your patience on this PR.
