fschneider@google.com e450dfb95a Add a smi-check instruction for arithmetic smi operations. 
The flowgraph optimizer inserts smi checks for the inputs of
arithmetic smi operations:

      PushArgument v0
      PushArgument v1
v2 <- InstanceCall(+, v0, v1) IC[1: Smi, Smi]

becomes

      CheckSmi(v0)
      CheckSmi(v1)
v2 <- BinarySmiOp(+, v0, v1)


Each input operand is checked separately. This avoids using a temp
register for a combined smi check. It also allows us to easily eliminate
the checks for left and right input separately.

There are two ways to eliminate smi checks:
1. By common subexpression elimination: if the value checked is already
   checked for smi-ness before.
2. By class-id propagation: If the input value is guaranteed to be a smi.

ager@google.com 4a397228dc Quick fix for SDK after Expando addition in the VM. 
Two files named expando.dart leads to one overwriting the other in
the SDK. Maybe we should use patching for Expando? In any case, we
are working towards not having the implementation file in the SDK
at which point we can revert this change.

containment in old-space domainates the running time of programs that
frequently invoke an old-space garbage collection.

Remove all optimized code whenever we load scripts/libraries/snapshots. Currently this occurs only when no Dart frame is live on stack. Future change (deoptimization) will allow dynamic class loading in presence of live Dart frames.
The cost of removing all optimized code is supposed to be low. If that assumptions turns out to be false I can add more elaborate tracking of optimized functions.
