Added a tool to more accurately count the lines of code. The previous
utility, getsrcs.sh suffered from two problems: (1) it generated command
lines too long for some platforms and (2) it searched the projects diretory
which now contains the llvm-test module (in nightly tester) but we don't
want to include the test code in our LOC calculation. This script should
be maintained as LLVM adds new top level directories that contain source
code.

Back to compiling land for v8

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/.

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.
