srdjan@google.com e632c8e383 Check class instruction supports Smi check. This fixes missed inlining of isOdd/isEven 
Fixed a nasty bug in equality optimization. Make sure that we emit CheckSmiInstr instead of CheckClassInstr if we are only checking for smi.

fschneider@google.com 058f8105d6 Small IL cleanup. 
1. Remove manual inlining and intrinsification of Double.toDouble
and Integer.toInt. The flow graph inliner can handle these since
they are not native library functions.

2. Remove unused member instance_call_ from UnarySmiOp.

fschneider@google.com 113e753734 Enable merging of comparisons into branches in checked mode. 
Instead of inserting an explicit type check at branches, the
branch instruction checks the input for boolean itself:

"if (a < b)" will be translated by the flowgraph builder
like this:

  CheckedBranch(a < b)

before it would look like this:

  t1 <- (a < b)
  t2 <- AssertBool(t1)
  Branch(t2 === true)


Also in this change:
flow_graph_optimizer.cc contains a small fix of an assert triggered when running with --trace-optimization.
