[LLVMdev] Reduced physical register limit in 3.1+?

I noticed that in LLVM 3.0 the limit of 16K physical registers was
removed, but it seems that this limit has returned in 3.1 with the use
of uint16_t for register ids.  Would it be possible to re-increase this
storage size to uint32_t or to change this to a typedef so that I can
patch it locally?
