  -----------
  [flang] Fix the trivial type passed as value with bind(C)

In the callee side, the value cannot be used directly. For example, the
dummy argument is lhs variable or the dummy argument is passed to
another procedure as actual argument.

Fix this by allocating one temporary storage and store the value. Then
map the symbol of dummy argument to the `mlir::Value` of the temporary.
