Done.  Bootstrap with "--with-build-config=bootstrap-lto" works fine.
I will commit this to trunk and wait for couple of days before
back-port to 4_9 branch.  Is that OK?

BTW, I found GCC trunk@213701 failed when building ada with below ICE
message, so I have to do the bootstrap with ada disabled.
