This is the next step towards preventing compiler from directly peeking into runtime and instead interact with runtime through a well defined surface. The goal of the refactoring to locate all places where compiler accesses some runtime information and partion those accesses into two categories: - creating objects in the host runtime (e.g. allocating strings, numbers, etc) during compilation; - accessing properties of the target runtime (e.g. offsets of fields) to embed those into the generated code; This change introduces dart::compiler and dart::compiler::target namespaces. All code in the compiler will gradually be moved into dart::compiler namespace. One of the motivations for this change is to be able to prevent access to globally defined host constants like kWordSize by shadowing them in the dart::compiler namespace. The nested namespace dart::compiler::target hosts all information about target runtime that compiler could access, e.g. compiler::target::kWordSize defines word size of the target which will eventually be made different from the host kWordSize (defined by dart::kWordSize). The API for compiler to runtime interaction is placed into compiler_api.h. Note that we still permit runtime to access compiler internals directly - this is not going to be decoupled as part of this work.
