  -----------
  [flang][hlfir] Make alias analysis trace through box designators. (#67353)

The changes are needed to get leslie3d same performance with HLFIR
as with FIR lowering. The two module allocatable variables cannot
alias, so the optimized bufferization should be able to elide
the temporary and inline the assignment loop.
