[PATCH, Fortran, alloc_poly, v1] Fix allocation of memory for polymorphic assignment

Hi Andre,

Two questions after quickly skimming over it ...

1) After adding that code block in gfc_trans_assignment_1, it seems
like the comment above is outdated, right?
2) Wouldn't it be better to move this block, which does the correct
allocation for CLASS variables, into
"alloc_scalar_allocatable_for_assignment", where the allocation for
all other cases is done?

Cheers,
Janus
