    cmd/compile: better check for single live memory · 256210c7
    Keith Randall authored
    Enhance the one-live-memory-at-a-time check to run during many
    more phases of the SSA backend. Also make it work in an interblock
    fashion.
    
    Change types.IsMemory to return true for tuples containing a memory type.
    
    Fix trim pass to build the merged phi correctly. Doesn't affect
    code but allows the check to pass after trim runs.
    
    Switch the AddTuple* ops to take the memory-containing tuple argument second.
    
    Update #20335
