I not sure if we can do this little by little. We would have to start
coding liblto to read and write the full IL and then port gcc to use
it.

That already exist. We have a section with the decls, but it is
impractical to parse trees out of gcc.

How about:

1) Commit a reviewed version of this.
2) Create the first part of the plugin (reading the symbols).
3) Start liblto.

I wouldn't start 3 until lto is fully capable. At least a bootstrap in
lto mode. We can start it earlier, but it will not get a lot of work
until gcc is ready to move to have its IL being handled by a library.
