can extract basic blocks up to the limit of the block extractor implementation.

llvm-svn: 13475

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 :)

 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.

wrapper idea uniformly: we can use Value::replaceAllUsesWith() instead of
special-casing by class of user.

* Wrap a long line

llvm-svn: 13061

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.

  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. :) :)
