jeanPerier 8252137b9a [flang] Lower struct ctor with character allocatable components (#79179)
There is no need to gather the length parameters from the parameter
symbols when facing a deferred length allocatable components in a
structure constructor, the length is set as part of the assignment given
the value.

Remove the checks for derived type runtime info symbols, this is not
relevant for what is being tested here.
