5e783ab0b5 Implement basic block extraction for the miscompilation debugger. This still needs
two things: the FIXME in ExtractBlocks needs to be implemented, and the basic block
extractor itself needs to have enough bugs fixed for this to be more or less
useful.

Until the time that this is generally useful, it is hidden behind the new bugpoint
-enable-block-extraction option.  I hope to get the FIXME done tonight.

Also of note, this patch adds a -extract-bbs option to bugpoint which can be used
to debug the block extractor.  (hint hint Misha :)

60083e2fc0 Use the new commandline flag to allow us to call bugpoint like this:
bugpoint ... --tool-args -enable-correct-eh-support -regalloc=linearscan --args -- -foo

So that tool-args option gets the -enable-correct-eh-support -regalloc=linearscan flags instead of bugpoint.

d11577b68b Add "Args" optional argument to AbstractInterpreter factory methods, which
fills in a ToolArgs vector in the AbstractInterpreter if it is set. This
ToolArgs vector is used to pass additional arguments to LLI and/or LLC.
This is intended to address Bug 40.

Also, make -debug-only=toolrunner work for the LLC and CBE
AbstractInterpreters.

de4803d0af As per Chris, greatly simplify handling of external functions by using the
wrapper idea uniformly: we can use Value::replaceAllUsesWith() instead of
special-casing by class of user.

dc7fef83dc Finally implement rewriting global initializers which use external functions
by creating an internal wrapper function with same signature as the external
function, and use it instead of the "real" function.

The wrapper then calls the external function using the same JIT function
resolution API that has been used before for rewriting instructions, since the
wrapper has an explicit call instruction which we can rewrite.

5313f23b8c Fix two pretty serious bugs:
1. Each time the loop extractor extracted a loop, we would leak a module.
  2. When we extracted a loop, we didn't add the new function to the list of
     miscompiled functions.  Thus if the bug was in a loop nest and we
     extracted it, we could actually *LOSE THE BUG*, which is very bad.

With these patches, bugpoint has successfully found a bug for me in a function
with several nested loops, and cut it down to just one of them. :) :)

a1cf1c8c87 After reducing a miscompiled program down to the functions which are being
miscompiled, try to use the loop extractor to reduce the program down to a
loop nest that is being miscompiled.  In practice, the loop extractor appears
to have too many bugs for this to be useful, but hopefully they will be fixed
soon...

efdc0b5057 Refactor and clean up a bunch more code. No major functionality changes.
* Make several methods of bugdriver global functions (ParseInputFile, PrintFunctionList)
 * Make PrintFunctionList truncate the output after 10 entries, like the crash debugger
   did.  This allows code sharing.
 * Add a couple of methods to BugDriver that allows us to eliminate some friends
 * Improve comments in ExtractFunction.cpp
 * Make classes that used to be friends up bugdriver now live in anon namespaces
 * Rip a bunch of functionality in the miscompilation tester into a new
   TestMergedProgram function for future code sharing.
 * Fix a bug in the miscompilation tester induced in my last checkin
