source dir for LLVM to be specified explicitly. This removes the dependency
on the llvm-config script. If the option is not given, then the scripts use
llvm-config which should be both built and in the PATH. This arrangement
provides a useful default for most developers but also allows the nightly
tester to execute countloc.sh before llvm-config is built and without
altering the PATH.

are considered to be code. This will give a drop in the LOC count on the
nightly testers, but it is more accurate than previous estimates.

1. Remove tabs
2. Wrap to 80 columns
3. Put spaces between "if" or "elsif" and expression
4. Put { on same line as if statement.
5. Make indentation be 2 spaces.
Functionality change:
Run utils/countloc.sh after the build is done. This is necessary because
that script now uses llvm-config to find the top src directory.

Not only will this take huge amounts of compile time, the resultant loop nests
won't be useful for optimization. This reduces loopsimplify time on
Transforms/LoopSimplify/2006-08-11-LoopSimplifyLongTime.ll from ~32s to ~0.4s
with a debug build of llvm on a 2.7Ghz G5.

pounding on Loop::contains (which is O(n) in the size of the loop), use a
sorted vector, which is O(log(N)) for each query. This speeds up Duraid's
horrible testcase from ~72s to ~31s in a debug build.

blocks that target loop blocks.
Before, the code was run once per loop, and depended on the number of
predecessors each block in the loop had. Unfortunately, scanning preds can
be really slow when huge numbers of phis exist or when phis with huge numbers
of inputs exist.
Now, the code is run once per function and scans successors instead of preds,
which is far faster. In addition, the new code is simpler and is goto free,
woo.
This change speeds up a nasty testcase Duraid provided me from taking hours to
taking ~72s with a debug build. The functionality this implements is already
tested in the testsuite as Transforms/CodeExtractor/2004-03-13-LoopExtractorCrash.ll.

the llvm source root from the llvm-config command. The dependency now is
that the correct llvm-config command is in the path. For most developers
this is the case.

particular directory, just pass that directory to the script. Also, clean
up the HTML output, put list of skipped dirs at the end, and make a few
other minor improvements.
