This seems reasonable, although I haven't given your patch a good look
yet. Before we put this in gold, though, you should post your proposed
change to the plugin interface (i.e., plugin-api.h) to the gcc-patches
mailing list for review there (please cc me), then be prepared to
update the whopr/driver wiki page on the GCC wiki:

https://gcc.gnu.org/wiki/whopr/driver

The patch to plugin-api.h will need to be applied first on the GCC
tree, then synced back to the binutils tree.

I'd suggest you also cc Sriraman Tallam (cc'ed here). The API
extensions for assigning sections to unique segments are his, so he
may have some useful feedback for you.
