42e83feba7 Initial checkin of a pass to lower packed operations to scalars operations. 
This also registers the pass with opt with a -lower-packed command line
option.

Patch contributed by Brad Jones.

911ec6d1c0 Bytecode Analyzer Cleanup: 
- Rearrange output order to make more sense
- Make only the function level output count as "detailed"
- Output dump output directly to stream, don't buffer it.
- Fix counting of block sizes
- Implement new handlers for number of types, dependent libs, target triple
- Compute the size of block headers.

4542c43761 Two Changes: 
- Pass the output stream to the analyzer so it can write its output there
  directly instead of buffering it.
- Don't pass a boolean to ParseBytecode because its not needed any more.

572c256519 Add boolean file format flags in preparation for version 5 bytecode. 
Remove the "processFunctions" boolean from ParseBytecode as it is no
longer needed. This is part of avoiding double reading of functions
when analyzing bytecode.

5b472d9879 Bytecode Reader Cleanup: 
- provide the correct conversion for ModuleBlockID in read_block (a potential
  bug but not actually exploited because reading module block ids doesn't
  use read_block).
- install support for handleTypeList handler
- install support for handleDependentLibrary handler
- install support for handleTargetTriple handler
- clean up comments, output strings,
- ensure that processing function arguments doesn't SIGSEGV if one of the
  arguments is a null pointer (yeah, it happened .. weird)
- prepare for version 5 bytecode by documenting what will change.

a96c4af7f1 Back out branchless SetCC code. While it helped a lot in some cases, it 
hurt a lot in others.  Instead, improve branching version of SetCC and
Select instructions.  The old code will be in CVS should we ever need to
dig it up again.

72cf7df6a3 Fix a nasty bug that Nate ran into. In particular, instead of emitting a 2+MB 
error message, print out:

llvm-link: error linking in 'g.2.rbc': Global Variable Collision on
' %struct.D_Reduction* %d_reduction_10_gram' - External linkage globals have
different initializers

That's a bit more concise, huh?
