Sync libiberty/ & include/ with GCC

Note this brings in the interface files for libcc1/G++ as well, which
we will be needing in GDB soon anyway.  That commit renamed a method
in the C interface and that required a small update to GDB's compile/
code, which I've included that in this patch to keep the tree
building.
