Also, LTO hasn't been merged from mainline in a long time; there will be a
big piece of work for whoever does the next merge from mainline to LTO.
One big piece of the tree representation changes on LTO branch (CALL_EXPR)
has been merged to trunk. Another big piece (TYPE_ARG_TYPES) hasn't, but
is still scheduled for Stage 1. The remaining pieces are smaller - and
many were preapproved for 4.3 - but I don't know what plans there are for
merging them to trunk.
Once all the tree representation changes are merged to trunk, that might
make a merge into LTO branch easier (in that all non-LTO-related conflicts
can be resolved by taking the trunk version).
