Do not allocate huge array in output_in_order.
We noticed that when analyzing LTRANS memory peak that happens right
after the start:
https://gist.github.com/marxin/223890df4d8d8e490b6b2918b77dacad
In case of chrome, we have symtab->order == 200M, so we allocate
16B * 200M = 3.2GB.
gcc/ChangeLog:
* cgraph.h: Remove leading empty lines.
* cgraphunit.c (enum cgraph_order_sort_kind): Remove
ORDER_UNDEFINED.
(struct cgraph_order_sort): Add constructors.
(cgraph_order_sort::process): New.
(cgraph_order_cmp): New.
(output_in_order): Simplify and push nodes to vector.
