Chris Lattner 6aee736d1b 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.

Brian Gaeke 4a278f0b1b Add --tool-args flag which lets you pass arguments to llc or lli.
This is intended to address Bug 40.

Misha Brukman ce89b392c6 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.

Misha Brukman 8301864215 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.

Chris Lattner dfbb1d1cfe Disambiguate symbols after loop extraction so that we can diagnose a code

Chris Lattner bf791614ed Merge the code generator miscompilation code into the optimizer miscompilation
code.  This "instantly" gives us loop-extractor power to assist with the
debugment of our nasty codegen issues.  :)

Chris Lattner a413b08580 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. :) :)

Chris Lattner bcec7875fb 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...

Chris Lattner fd72bed301 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
