fortran: [PR121628] 

The PR121628 deep-copy helper reused a static seen_derived_types set
across wrapper generation, so recursive allocatable arrays that appeared
multiple times in a derived type caused infinite compile-time recursion.
Save and restore the set around each wrapper build, polish follow-ups,
and add a regression test to keep the scenario covered.

gcc/fortran/ChangeLog:

	PR fortran/121628
	* trans-array.cc (seen_derived_types): Move to file scope and
	preserve/restore around generate_element_copy_wrapper.
	* trans-intrinsic.cc (conv_intrinsic_atomic_op): Reuse
	gfc_trans_force_lval when forcing addressable CAF temps.

gcc/testsuite/ChangeLog:

	PR fortran/121628
	* gfortran.dg/alloc_comp_deep_copy_7.f90: New test.

libgfortran/ChangeLog:

	PR fortran/121628
	* Makefile.in: Keep continuation indentation within 80 columns.
	* aclocal.m4: Regenerate.
	* libgfortran.h: Drop unused forward declaration.
