Martin Kustermann 0f76981bb1 [vm/concurrency] Change references to class_table/object_store/heap from Isolate to IsolateGroup
As part of making the compiler and other subsystems independent
of `Isolate` we have to move various state from `Isolate` to
`IsolateGroup`.

The class_table and object_store were already moved to `IsolateGroup`.

This CL only replaces usages of `Isolate::{object_store,class_table}`
with the equivalent in `IsolateGroup`.

Issue https://github.com/dart-lang/sdk/issues/36097

TEST=Pure refactoring - relying on existing test coverage.

Vyacheslav Egorov f496e538f4 [vm] Decouple assemblers from runtime.
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.

Erik Corry 1dec18e2cf [VM] Make x64 assembler more regular
Apart from removing almost 1000 lines of very repetitive code, the idea here is
to change the assembler from a huge pile of arbitrary code into something that
can be used to generate tables of opcodes and their structure. Later, I'd like to
use this to make the disassembler more table driven and less arbitrary, and
perhaps build an x86 simulator in the same vein as the ARM simulator, which
would help me debug (I find the ARM simulator very useful when making low level
changes to the VM and miss its functionality on x86).

Erik Corry d300b08e35 [VM] Use X64 disassembler for IA32 and X64 (reland)
R=vegorov@google.com

This removes the IA32 disassembler and uses the X64 disassembler for
both variants.  Instructions that were in the IA32 assembler, but not
supported by the X64 disassembler have been added.  It also adds some
regression tests for a lot of the disassembler output.
