Clean up the 'check' CMake build rule a bit, notable renaming it to
'check-llvm'.

Don't worry! 'check' still works! =] To rationalize the names of targets
used to run tests, the vague plan is the following:

make check-llvm  # run LLVM reg/unit tests  (currently 'check')
make check-clang # run Clang reg/unit tests (currently 'clang-test')
make check-rt    # run CompilerRT reg/unit tests

make check-tsan  # run TSan reg/unit tests (subset of -rt)
make check-all   # run as much of the above as is available

The last one respects what projects are checked out and built for
a given tree. Personally, I would like to eventually make 'check' be an
alias for 'check-all'. For now however, it is an alias for 'check-llvm',
and thus no behavior has changed.

While this patch and my plan only really apply to CMake, I think it
might be good to similarly rationalize the naming scheme for the Make
builds.

Enable the new LoopInfo algorithm by default.

The primary advantage is that loop optimizations will be applied in a
stable order. This helps debugging and unit test creation. It is also
a better overall implementation without pathologically bad performance
on deep functions.

On large functions (llvm-stress --size=200000 | opt -loops)
Before: 0.1263s
After:  0.0225s

On deep functions (after tweaking llvm-stress, thanks Nadav):
Before: 0.2281s
After:  0.0227s

See r158790 for more comments.

The loop tree is now consistently generated in forward order, but loop
passes are applied in reverse order over the program. If we have a
loop optimization that prefers forward order, that can easily be
achieved by adding a different type of LoopPassManager.
