* *** 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.

* Change getVarInfo to take real virtual register numbers and offset them
  itself.  This has caused me so much grief, it's not even funny.

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.

* 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.
