bitfield lowering? What is the status of lra, reload-2a, pph,

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.
