This commit adds a new feature called find-bugs. The find-bugs option can be invoked on a .bc file from the command like with -find-bugs and a list of passes you wish to test. This procedure takes the set of optimization passes the user specifies, randomizes the passes, runs the passes on the specified .bc file, compiles the program, and finally runs the program checking its output vs the .bc file with no optimizations. This process repeats until either the user kills bugpoint or an error occurs in the optimizations, program complitation, or the running of the program. If an error occurs, bugpoint attempts to diagnose the error by eliminating passes that are not at fault and code that is not needed.

Make all tools that use llvmdo have a -topdir option that allows the top
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.

Added some comments to clarify code around sub TestDirectory

1. fix bug by ensuring we start at the llvm source root.
2. make use of the -code-only option on llvmdo
3. Add some debug print statements to find #1

Count the documentation. Otherwise we take a 30,000 hit in the LOC on the
nightly test graph. And, documentation is important.

Use the new -code-only option to llvmdo so that we only count things that
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.

Add a -code-only option which restricts llvmdo to visiting just those
files that are considered to be code. Documentation is excluded.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29652 91177308-0d34-0410-b5e6-96231b3b80d8

Changes for LLVM coding standard compliance:
  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.

Emit .set directives for jump table entries when possible, which reduces
the number of relocations in object files, shrinkifying them.

Fix a bug in a recent refactoring that broke a bunch of stuff.

Fix an obvious bug, noticed by inspection.  No current targets trigger this.

Don't attempt to split subloops out of a loop with a huge number of backedges.
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.

New testcase, this used to take hours to loopsimplify.
