4295e81138 Don't just assume that either uint64_t or u_int64_t is available. Instead, 
give preference to uint64_t if it exists. If not, check for u_int64_t. If
that doesn't exist either, then error out.

2676000067 Change the way we choose a free register: instead of picking the first 
free allocatable register, we prefer the a free one with the most uses
of inactive intervals.

999a10318f Change the way we choose a free register: instead of picking the first 
free allocatable register, we prefer the a free one with the most uses
of inactive intervals. This causes less spills and performes a bit
better compared to gcc:

c4abcbefb1 Changes For Bug 352 
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

e7e63c8da4 Be a bit more efficient when processing the active and inactive 
lists. Instead of scanning the vector backwards, scan it forward and
swap each element we want to erase. Then at the end erase all removed
intervals at once. This doesn't save much: 0.08s out of 4s when
compiling 176.gcc.
