            Bug ID: 35179
           Summary: Merge r312292, r312296 into the 5.0 branch: Fix for
                    PR34398: assert with random access iterator if the
                    step>1.
           Product: OpenMP
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: release blocker
          Priority: P
         Component: Clang Compiler Support
          Assignee: unassignedclangbugs at nondot.org

            Blocks: 34492

If the loop is a loot with random access iterators and the iteration
construct is represented it += n, then the compiler crashed because of
reusing of the same MaterializedTemporaryExpr around N. Patch fixes it
by using the expression as written, without any special kind of
wrappings.

Note: I'm not really sure if we should merge this one: It touches quite a few
tests and needs the second commit to fix the test. Just marking this for
discussion, feel free to close if we don't want to merge it.
