There's nothing about SSA that makes any of those things harder.

In any case, the use of SSA is fairly fundamental to GCC's current
architecture.  You have a habit of just showing up and telling
people to throw out all their work and start over, based on no
evidence.  That's why you often get a hostile reception.
