Currently when reading in LTO sections from ld -r files they can
get randomly reordered based on hash tables and random IDs.
This causes reordering later when the final code is generated and
also makes crashes harder to reproduce.
This patch maintains explicit lists based on the input order and uses
those lists to preserve that order when starting the rest of the
LTO passes.
This is the first step to working -fno-toplevel-reorder for
LTO. But this needs more changes because the LTO partitioner
can still reorder.
This add two lists: one for the section and another one for
the file_decl_datas. This is needed because the sections are
walked twice through different data structures.
In addition some code becomes slightly cleaner because we don't need
to pass state through abstract callbacks anymore, but
can just use direct type safe calls.
