bitfield lowering?  What is the status of lra, reload-2a, pph,
cilkplus, gupc (I assume at least some of these are 4.8+ material)?

The bits on reload-v2a provide range splitting and a second chance at assigning a hard reg for unallocated allocnos. The code has been very stable and shows a small improvement on x86/x86_64. The biggest concern I have with the code is the compile-time performance, which I know is bad, but I haven't done any serious measurements.
