The plan right now is to drop SSA_NAME_EQUIV and instead re-use the
existing SSA_NAME_VALUE field.  This is going to take a little bit
more work in the short term, but I'm pretty sure it's the right
thing to do in the longer term.

Rather than just churn the definition of SSA_NAME_EQUIV, I'm going 
to focus on getting us to the point where we can use the
SSA_NAME_VALUE field.
