c6eab62a9e Fix bug: CBackend/2003-05-13-VarArgFunction.ll 
In C, a prototype with no arguments is varargs.  A prototype that takes void
has zero args.

e78921f048 * 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.

a8497e3094 * 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.

46f2fc75da Make sure that globals are emitted AFTER the passmanager is set up for the JIT, 
because the globals may refer to functions that need to be compiled!
