05d5a44c02 Do not use .xword and friends to emit zeros on V9. Apparently there are issues 
with emitting .xwords when not on an 8-byte boundary (.xword 0 is not the
same as 8 .byte 0's).  Because we do not know when or when we are not aligned,
just emit bytes like the old V9 asmprinter did.

8a934d5632 Moved the "SmallExamples" out of the /projects directory and into a new 
/examples directory. History was maintained. These programs do not need to
be configured but things in /projects must be.

7117a132ea Initial checkin of a pass to lower packed operations to scalars operations.

d7d70bdccb 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.

84d4e1b105 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.

c0868628e0 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.

09976167c1 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.

0d6613d183 Dump the DependentLibsBlockID, its not a block, its just a list inside the 
globals info block. Add an enumerator for getting the number of enumerators
so we can range check in assertions.

e6aace2ecb 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.

f6a56abd4d Bytecode Analyzer cleanup: 
- don't save the "dump" output, just emit it
- record the bc version number
- record info about the dependent libraries and target triple
- use the correct enumeration as the index on the block size map
