iposva@google.com 070d3dedf7 - Add a per-isolate pseudo random number generator to the 
VM internals. This PRNG is not used to generate random
  numbers in Dart code.
- Use the PRNG to generate JIT cookies for large constants
  if needed during assembly.
- Add the possibility to set an external entropy source
  for the PRNG through the C API.

fschneider@google.com 86da5111ad Replace scalarlist optimizations and split external array loads into two IL instructions. 
This CL removes optimized access for scalarlist, and only the new TypedData classes
are optimized. I changed the runtime libraries core and math to use typedData
instead of scalarlist (Uint16List is used in StringBuffer, Uint32List by Math.random).

Instead of using LoadIndexed for internal and external arrays,
split external loads into a load of the backing store and a load
of the element.

v3 <- LoadIndexed(v1, index)

becomes

v2 <- LoadUntagged(v1, ExternalTypedData::data_offset)
v3 <- LoadIndexed(v2, index);

For this I introduce two new representations in the IL:

 kUntagged (for values that hold a untagged pointer) and
 
 kNoRepresentation (for instructions accept any input
 representation)

Deoptimization does not need to know about kUntagged
since these values can never occur in the environment.

Also with this change:
* fix COMPILE_ASSERT and use it in one place.
* Cleanup IL printer output of deopt ids.

simply redirect to the static methods.
They will be removed in time (when library code is ready for it).
