      Fixed linear regalloc bug, dropped some tracing code · c62b824e
      dias@eecs.harvard.edu authored
      o The linear-scan register allocator sometimes allocated a block
        before allocating one of its predecessors, which could lead
        to inconsistent allocations. Now, we allocate a block only
        if a predecessor has set the "incoming" assignments for the block
        (or if it's the procedure's entry block).
      o Also commented out some tracing code on the new codegen path.

      Clarify the SRT building process · e367ebeb
      dias@eecs.harvard.edu authored
      Before: building a closure that would build an SRT given the top-level
      SRT. It was somewhat difficult to understand the control flow, and it
      may have had held onto some data structures long after they should be dead.
      Now, I just bundle the info we need about CAFs along with the procedure
      and directly call a new top-level function to build the SRTs later.
