Native resources allocated by v8, as internal implementation detail,
and held by a Foreign object, must be released when the Isolate is
torn down. Example: wasm::WasmModule allocated by wasm compile, and
held throughout the lifetime of the WebAssembly.Module object.
This change:
- Extends Managed<CppType> with a mechanism for doing just that
- Separates the role of Managed<CppType> to be strictly an owner of
the lifetime of the native resource. For cases where that's not
desirable, we can polymorphically use Foregin.
- moves managed.h out of wasm, since it's not wasm-specific.

This CL implements ldrex, ldrexb, ldrexh, strex, strexb, and strexh in the
Simulator. These instructions provide "exclusive" access, which provides mutual
exclusion for concurrent threads of execution.
The ARM specification gives some leeway to implementors, but essentially
describes each processor as having Local Monitor and Global Monitor. The Local
Monitor is used to check the exclusivity state without having to synchronize
with other processors. The Global Monitor is shared between processors. We
model both to make it easier to match behavior with the spec.
When running with multiple OS threads, each thread has its own isolate, and
each isolate has its own Simulator. The Local Monitor is stored directly on the
Simulator, and the Global Monitor is stored as a lazy singleton. The Global
Monitor maintains a linked-list of all Simulators.
All loads/stores (even non-exclusive) are guarded by the Global Monitor's mutex.

The deprecated pipeline is used for asm.js only, where we forcibly
disable inlining anyways (for performance reasons), so inlining via
the AstGraphBuilder is essentially dead code by now, thus there's no
point in trying to keep that around in the code base.
Also nuke the test-run-inlining.cc file, which would require some heavy
surgery (for probably little benefit), and move the useful tests for
mjsunit tests instead.

The new AccessorAssembler encapsulates all the functionality that's
specific to building LoadIC/StoreIC stubs.
There are two header files (accessor-assembler.h and
accessor-assembler-impl.h) so that clients of the assembler can include
the one, and subclassing assemblers can include the other.

Use sparingly!
This doesn't add any really new functionality, other than making it more
convenient to do this.
This will primarily be used to wrap a WasmModule to be referenced from a
JSObject that represents an instance. There is one WasmModule C++ object
per parsed WasmModule, so this should not be more than a handful or a few
dozen in well-behaved programs.

This introduces a new OsrGuard node that is inserted during graph building
to guard the inferred type of the OSR value.
The type of the OSR value is inferred by running the typer before OSR
deconstruction, and then taking the type from the phi that takes the
OSR value. After the deconstruction, we throw the types away.
At the moment we only support the SignedSmall OSR type and we always
pick the tagged representation. Later, we might want to support more
types (such as Number) and pick better representations (int32/float64).
This CL also removes the OSR deconstruction tests because they build
unrealistic graph (no effect chain, no loop termination). I considered
adding the effect chains to the tests, but this would make the tests
even more brittle.
