  Log Message:
  -----------
  [flang][runtime] Handle conflicts for derived types with dynamic components.

When creating a temporary for conflicting LHS and RHS we have to deep copy
the dynamic (allocatable, automatic) components from RHS to the temp.
Otherwise, the conflict may still be present between LHS and temp.

gfortran/regression/alloc_comp_assign_1.f90 is an example where the current
runtime code produces wrong result:

  [flang] Fixed shape computation for elementals with optional dummys.

It looks like a regression after D151737: shape of the elemental
call became rank-0.
