This patch implements the runtime semantics of static public
class fields.
Adds a new InitializeClassFieldsStatement AST node that contains
all the static class fields and their initializers.
ClassLiteral is now desugared to be included in a do-exp that calls
an initializer function which contains this new AST node.

This CL adds a first implementation of Liftoff, the new wasm baseline
compiler, for x64 and ia32. It currently supports the most important
i32 instructions and control instructions. Whenever it encounters an
instruction it does not support yet, it aborts.
In a subsequent CL, Liftoff will be called from the
WasmCompilationUnit, falling back to Turbofan compilation if the
baseline compiler bails out.

This adds a new InstanceOfIC where the TestInstanceOf bytecode collects
constant feedback about the right-hand side of instanceof operators,
including both JSFunction and JSBoundFunction instances. TurboFan then
uses the feedback to optimize instanceof in places where the right-hand
side is not a known constant (known to TurboFan).
This addresses the odd performance cliff that we see with instanceof in
functions with multiple closures. It was discovered as one of the main
bottlenecks on the uglify-es test in the web-tooling-benchmark. The
uglify-es test (run in separation) is ~18% faster with this change.
On the micro-benchmark in the tracking bug we go from
instanceofSingleClosure_Const: 69 ms.
instanceofSingleClosure_Class: 246 ms.
instanceofMultiClosure: 246 ms.
instanceofParameter: 246 ms.
to
instanceofSingleClosure_Const: 70 ms.
instanceofSingleClosure_Class: 75 ms.

boosting performance by roughly 3.6x and thus effectively removing the
performance cliff around instanceof.

There are wasm operations which operate on floats or double, but they
need to preserve the exact bit pattern. Thus they cannot be stored and
passed as float or double, since that might flip the signaling NaN bit.
This CL extends WasmValue to store floats and doubles as bit pattern,
and adds accessors to extract them as Float32 or Float64.
The interpreter is changed to execute certain operations (i32.abs,
i32.neg, i64.abs, i64.neg, f32.reinterpret/i32, f64.reinterpret/i64) on
boxed floats.

This introduces unreachable state into load elimination. We mark state
as unreachable if we know statically that a map check would fail.
When processing effect phis, we disconnect unreachable state's
control from the effect phi's merge, and point it to RuntimeAbort.
The control input to the merge is then updated with Dead. Dead
code elimination prunes the merge, phis and effect phis.

The spec got rid of `CheckObjectCoercible` a while back, and so should
we. This change is not observable in most of the affected cases since
`ToObject` is up near the top of most Array method algorithms. An
example of an observable effect of this change occurs for the following
input:
Array.prototype.sort.call(null, 1);
Behavior before applying the patch (incorrect message):
TypeError: Array.prototype.sort called on null or undefined
Expected behavior:
TypeError: The comparison function must be either a function or
undefined
This patch removes `CheckObjectCoercible` and adds tests to ensure the
few observable cases are addressed correctly.
The patch also adds a missing `ToObject(this)` to
`Array.prototype.lastIndexOf` which would otherwise become observable
as a result of `CheckObjectCoercible` being removed.

The motivation for the new field is to provide race-free way to
iterate used in-object properties of a JSObject in concurrent marker.
This CL keeps the new field in sync with the unused_property_fields
and subsequent CL will remove unused_property_fields.

Arm64's implementation of `TurboAssembler::Abort()` supports printing the
bailout reason to the standard output without calling to the runtime. For this
to work, we need access to the host's printf function so we can call it
directly. In the general case, `Abort` does call the runtime, however, we cannot
do it if we want to abort from inside CEntryStub.
