PR fortran/98307 - Dependency check fails when using "allocatable"
The dependency check for FORALL constructs already handled pointer
components to derived types, but missed allocatables. Fix that.
gcc/fortran/ChangeLog:
PR fortran/98307
* trans-stmt.c (check_forall_dependencies): Extend dependency
check to allocatable components of derived types.
gcc/testsuite/ChangeLog:
PR fortran/98307
* gfortran.dg/forall_19.f90: New test.
