1d82003535 Just some code beautification changes I had sitting around in my tree.

127a46eeba 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.

1db4cefc28 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.

eb2bc51e49 * Convert to use LiveVariable analysis 
* Convert to use PHIElimination pass
* Don't spill values which have just been reloaded (big win reducing spills)
* Add experimental support for eliminating spills before TwoAddress
  instructions.  It currently is broken so it is #ifdef'd out.
* Use new "is terminator" flag on instructions instead of looking for
  branches and returns explicitly.
