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.

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/.

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.

investicated further as the linearscan variants don't really need

LiveInterval>. This saves some space and removes the pointer
indirection caused by following the pointer.
