Original Commit Message:
"Extend the code-generator tests to cover AssembleMove and AssembleSwap with
Simd128 registers and stack slots, for targets that support them.
For this to work however, we need support for passing Simd128 stack parameters
in TurboFan which this patch implements for Arm and x86. PPC and S390 both do
not support the Simd128 representation and it appears MIPS and MIPS64's
implementation of AssembleMove and AssembleSwap do not support it either.
As per the design of the tests, the set of values to perform moves on are
represented in a FixedArray of Smis (for kTagged) and HeapNumbers (for kFloat32
and kFloat64). They are converted to raw values for the moves to be performed
on, to be then converted back into a FixedArray. For the kSimd128
representation, we represent values as a FixedArray of 4 Smis, each representing
a lane. They are converted to a raw Simd128 vector using the `I32x4ReplaceLane`
and `I32x4ExtractLane` operations.
Finally, these tests need Simd128 variables mixed with the CodeStubAssembler
which is not a use-case officially supported. And as a result, the `RecordWrite`
stub does not guarantee to preserve Simd128 registers. To get around this, we
have to be careful to skip write barriers when dealing with Simd128 parameters
inside the "teardown" function, and we've had to move all allocations to the
"setup" function.
Thanks to this, we are able to catch bugs such as this one
https://bugs.chromium.org/p/v8/issues/detail?id=6843."

The catch prediction logic got confused when we merged the reactions and
result fields of JSPromise, because for settled promises it would start
to treat the result as reactions list, leading to a crash most likely or
memory corruption in the worst case (only if break on uncaught exception
is enabled). We can only inspect reactions when the promise is still in
"pending" state.

This adds a new isolate wide Promise#then protector, which guards the
"then" lookup for all JSPromise instances whose [[Prototype]] is the
initial %PromisePrototype%. Thus arbitrary mutations to the
Promise.prototype (i.e. monkey-patching other methods or installing
new functions) no longer sent you down the slow-path. Use this protector
in Promise.prototype.catch and in Promise.resolve.
Drive-by-fix: Restructure the resolve logic a bit and avoid the
expensive and large SameValue check, which can be turned into a simple
reference equal, as the promise in there is known to be a JSPromise
anyways.

This change does not modify generated bytecode (but maybe it should to
take advantage of load IC feedback for loading "next"). Doing this grows
bytecode by quite a bit, since it's necessary to throw-if-not-an-object
before loading "next" (which currently gets to live in a code stub

This creates a uniform PerformPromiseThen builtin, which performs the
operation with the same name from the spec, except that it expects the
handlers to be either undefined or callable already, since this is only
relevant for a single callsite (namely Promise.prototype.then).
Introduce a matching operator JSPerformPromiseThen into TurboFan, which
represents this operation and removes the additional checks in case of
Promise.prototype.then based on the information we can derived from the
receiver maps.
This yields a nice 20-25% improvement on Promise.prototype.then, as
illustrated by the following micro-benchmark
```js
const N = 1e7;
function inc(x) { return x + 1; }
function chain(promise) {
return promise.then(inc).then(value => {
if (value < N) chain(Promise.resolve(value));
});
}
console.time('total');
chain(Promise.resolve(0));
setTimeout(console.timeEnd.bind(console, 'total'));
```
which goes from around 1230ms to 930ms with this patch.

Replace hard-coded uses of `kScratchDoubleReg`, `kScratchDoubleReg2` and
`kScratchQuadReg` with the safer `UseScratchRegisterScope`. The reason for doing
this is to be able to safely use these scratch registers inside the assembler
without having to worry about the code generator using them too.
For instance, using this scope showed us that `TryInlineTruncateDoubleToI` is
using a FP scratch register while the caller, the `DoubleToI` stub, is using it
too. We are safe only because the stub passes the scratch register to
`TryInlineTruncateDoubleToI` as an input. Using the scope forces us to
explicitely use the input register instead of acquiring a new scratch.

Instead of inlining NewPromiseCapability everywhere, we should have it
as a separate builtin that can be called. The motivation for doing so is
to reduce the overhead of the builtins and just share the slow-path
handling in a single place, plus this way we can also utilize the
NewPromiseCapability functionality from TurboFan optimized code
eventually.
Also remove the unused %new_promise_capability intrinsic and the builtin
backing it.
