[Bug fortran/40877] New: memory leaks with gfc_charlen?

[janus at gcc dot gnu dot org]

This PR is a reminder to check some places where a new gfc_charlen is allocated
without properly setting it into a namelist (ns->cl_list). Each of them may
potentially produce a memory leak (though I'm not completely sure):

 * expr.c (simplify_const_ref)
 * symbol.c (gfc_set_default_type, generate_isocbinding_symbol)
 * trans-decl.c (create_function_arglist)

I noticed them while working on PR40822, where I also introduced the function
gfc_new_charlen, which should be used instead of gfc_get_charlen to avoid
memory leaks.
