91a452b382 * 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.

600dee4aae * Convert to be a MachineFunctionPass instance 
* Use new FunctionFrameInfo object to manage stack slots instead of doing
  it directly
* Adjust to new MRegisterInfo API
* Don't take a TM as a ctor argument
* Don't keep track of which callee saved registers are modified
* Don't emit prolog/epilog code or spill/restore code for callee saved regs
* Use new allocation_order_begin/end iterators to simplify dramatically the
  logic for picking registers to allocate
* Machine PHI nodes can no longer contain constant arguments

* Use a bitvector to keep track of registers used instead of a set
* Fix problem where explicitly referenced registers would be added to
  regsused set and never removed
