kmillikin@google.com a119414b2f Cache lookups at megamorphic call sites in optimized code. 
The function name and argument descriptor are mapped to a lookup cache
at compile time.  The cache maps class id to target function.  It is
resizable.

kmillikin@google.com c9bab9efaa Do not call ResolveCompileInstanceFunction from the lookup stub. 
The InstanceFunctionLookup stub is only called after the inline cache miss
handler.  The miss handler ensures that ResolveCompileInstanceCallTarget is
called.

instructions at the call site.  This previous approach becomes unwieldy when

srdjan@google.com 85cf9af6ab Fix for issue 6678: Result of identical(a, b) with a and b doubles not consistent. 
Implement proposed new identity spec (flag --new_identity_spec). It will be enabled/committed once the new spec been confirmed.

The new spec says that identity of numbers is computed on their values instead of on the object reference. This provides deterministic behavior without having to disable optimizations in the VM. In some cases 'identical' is now slower than 'equality' as more checks need to be done. The VM compiler can optimize 'identical' in the future.

My benchmarks do not show any slow down.

srdjan@google.com 7375693321 In optimized code use IC calls for instance calls that have no IC data instead of deoptimizing. The optimized IC call increments usage counter and reoptimizes optimized function if the threshold is met. 
Recognize closure calls and mark them in ICData. Closure calls do not populate ICData, i.e., number of checks is always 0 (unless mixed closure calls with regular instance calls). Therefore closure IC calls do not count for reoptimization.
