Fixed linear regalloc bug, dropped some tracing code 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.
