Patrick Jenkins c46c03834c 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.

Chris Lattner 20ec1654b1 Teach bugpoint to kill optimization passes that run over the timeout limit,
which allows it to debug optimizer infinite loops.  This patch is contributed
by Nick Lewycky, thanks!

Reid Spencer 842118ce95 For PR351:
Generally, remove use of fork/exec from bugpoint in favor of the portable
sys::Program::ExecuteAndWait method. This change requires two new options
to bugpoint to tell it that it is running in "child" mode. In this mode,
it reads its input and runs the passes. The result code signals to the
parent instance of bugpoint what happened (success, fail, crash).

This change should make bugpoint usable on Win32 systems.

Chris Lattner beb01faea3 When the user hits ctrl-c, bugpoint should attempt to stop reduction as
quickly as possible and output what it has so far.  If they hit it twice,
bugpoint is killed.

* Place a try/catch block around the entire tool to Make sure std::string
  exceptions are caught and printed before exiting the tool.
* Make sure we catch unhandled exceptions at the top level so that we don't
  abort with a useless message but indicate than an unhandled exception was
  generated.

Misha Brukman d792c9bb46 Major addition to bugpoint: ability to debug code generators (LLC and LLI).
The C backend is assumed correct and is used to generate shared objects to be
loaded by the other two code generators.

LLC debugging should be functional now, LLI needs a few more additions to work,
the major one is renaming of external functions to call the JIT lazy function
resolver.

Bugpoint now has a command-line switch -mode with options 'compile' and
'codegen' to debug appropriate portions of tools.

ExecutionDriver.cpp: Added implementations of AbstractInterpreter for LLC and
GCC, broke out common code within other tools, and added ability to generate C
code with CBE individually, without executing the program, and the GCC tool can
generate executables shared objects or executables.

If no reference output is specified to Bugpoint, it will be generated with CBE,
because it is already assumed to be correct for the purposes of debugging using
this method. As a result, many functions now accept as an optional parameter a
shared object to be loaded in, if specified.
