Fixed compilation errors, command-line argument declarations, cleaned up code to

look nicer and removed useless stuff.
Also renamed a few variables, moved them into namespaces, converted outputting
to a file into a print to std::cerr with a DEBUG() guard, as all passes should
do anyway.
No functional changes have been made. However, this code now compiles.

Initial checkin of PRE on LLVM. This implementation is still lacking in
...
several ways:
* Load expressions are not PRE'd well. Alias Analysis should be used to
get accurate information when computing anticipatibility.
* The expression collection implementation does not handle PHI nodes properly,
thus the implementation misses many opportunities to PRE.
* This code could be sped up quite a bit
Despite these flaws, the code seems to work well, and handles PR's as one
would expect.

Changes to the V2 bytecode format:
...
- Null values are implicitly encoded instead of explicitly, this makes
things more compact!
- More compactly represent ConstantPointerRefs
- Bytecode files are represented as:
Header|GlobalTypes|GlobalVars/Function Protos|Constants|Functions|SymTab
instead of
Header|GlobalTypes|Constants|GlobalVars/Function Protos|Functions|SymTab
which makes a lot of things simpler.
Writer changes:
- We now explictly encode versioning information in the bytecode files.
- This allows new code to read bytecode files produced by old code, but
new bytecode files can have enhancements such as the above. Although this
makes the reader a bit more complex (having to deal with old formats), the
writer only needs to be able to produce the most recent version.
