One way could be to move the "EXPR_ASSIGN:" part of trans-stmt.c's
gfc_trans_forall_1 into a separate function and add a "EXPR_BLOCK:" which loops
over all c->block->next, calling that new function (with an gcc_assert that it
only contains EXPR_ASSIGN); it probably deserves also a comment that the BLOCK
is generated by the FE optimization.
