* *** 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.

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.
