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.

hausner@google.com 8e499806e8 Revise duplicate interface check 
Move check for duplicate interfaces from parser to class finalizer.
The parser only compared interfaces by name, which did not work
properly for qualified (imported) names. Now the check happens in the
class finalizer after types are finalized.

Sadly, our test harness does not appear to know how to handle multitests
that import libraries.

hausner@google.com ed2e198b99 Mixins with Generics 
This change adds support for generics to mixins. It's not a particularly elegant
implementation, so I expect to change how it works internally in later checkins.

Also, there is still one aspect of the implementation that is incorrect. In the
case of typedef, the newly introduced name is not yet an alias for  the
mixin application. Instead, the MA is a superclass of the typedef name. That
will need to be fixed in a later checkin. I don't want to make this change
bigger.

fschneider@google.com f1fa8c68c2 Fix bug in optimized byte array views on tranferable backing stores. 
This affects views when using scalarlist: The code generated
did not take the receiver class into account correctly,
so it only works for internal byte arrays.

For now, I just disable optimization for external backing stores.

The optimization will be added again for TypedDataViews in a future CL.

This is a preparation CL for supporting try-catch in optimized code. Until

This meant carrying around handler_types_ and catch_try_index_ for blocks
that are not catch blocks which is not needed.

For now, CatchBlockEntry behaves the same as TargetBlockEntry except for
the additional members needed for catch blocks.
