Hello,
this is another small cleanup I had lying around.
Regression-tested on x86_64-linux. Ok for master?

Remove the special handling of end of nested scalarization chains, which
advanced the chain to an element of a parent chain when the current one
was reaching its end.
That handling was superfluous as nested chains correspond to nested
scalarizations of subexpressions and the scalarizations don't extend beyond
their associated subexpression and don't use any scalarisation element from
the parent expression.
No change of behaviour, as the GFC_SE struct is supposed to be in its final
state anyway when the last element from the chain has been consumed.
gcc/fortran/ChangeLog:
* trans-expr.cc (gfc_advance_se_ss_chain): Don't use an element
from the parent scalarization chain when the current chain reaches
its end.
