In many cases, the Mutexes and Monitors have to be marked "mutable"
because they're used to synchronize const accessor methods.

The interpreter only build of the Dart VM should not be including any
sources from the 'compiler' directory.
First part of restructuring sources to enable an interpreter only build
of the VM
- Move CompileClass from compiler.cc file to class_finalizer.cc

Previously, the background compiler was deleted by the thread pool, which could have raced ahead of the mutator clearing its reference. Now it is deleted by the mutator.

Previously we could hit an assert when for instance "42 ~/ 0"
was being optimized by the background compiler. The reason was
that we assert that we're on the "mutator thread" when allocating
memory (which is done as we're evaluating the code - and we're
trying to evaluate it again because evaluating it gives an error,
and errors aren't cached).
However, to create a test for this it would be better if we could
make it always crash, i.e. use something like
```
--optimization_counter_threshold=5 --no-background-compilation
```
to force an optimization, but still make it crash dispite the
optimization happening in mutator thread (because of
--no-background-compilation).
This CL propagates if we're optimizing to the kernel builder,
and in the constant builder further more asserts that we're not.
Additionally it introduces a test that shows the crash and fixes it.

New folder structure (nested under vm/):
- compiler/
- jit/ - JIT specific code
- aot/ - AOT specific code
- backend/ - all middle-end and back-end code (IL, flow graph)
- assembler/ - assemblers and disassemblers
- frontend/ - front ends (AST -> IL, Kernel -> IL)
compiler/README.md would be the documentation root for the compiler
pipeline
