  Changed paths:
    M flang/lib/Optimizer/Transforms/LoopVersioning.cpp
    M flang/test/Transforms/loop-versioning.fir

  Log Message:
  [flang] Skip OPTIONAL arguments in LoopVersioning.

This patch fixes multiple tests failing with segfault due to accessing
absent argument box before the loop versioning check.
The absent arguments might be treated as contiguous for the purpose
of loop versioning, but this is not done in this patch.
