b52e0241c0 Use a kill, not a dead definition, update comment

572c770668 * Keep LiveVariable information more up-to-date and consistent 
* *** Finally mark values that are inputs to PHIs as killed when appropriate.
   This should make the generated code quite a bit better.  For example, the
   local-ra will not have to spill PHI inputs at the end of predecessor BB's
   anymore.

fb2cb69dc5 * Keep the BBMap around as long as the pass is live 
* Change getVarInfo to take real virtual register numbers and offset them
  itself.  This has caused me so much grief, it's not even funny.

2c821cc06e 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.

8baa01c1d7 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.

  branches and returns explicitly.
