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.

Made the code readable:
...
* Lines must be wrapped at 80 chars. This is a hard limit.
* Consistent style on functions, braces, if, for, etc. Code must be readable.
No functional changes have been made, even though I added a new typedef.

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.
