If there is no constructor or species updates on Array or TypedArrays,
then skip lookups of constructor and species so that we can create a new
typed array quickly. This path makes TA.p.slice() 2x faster in fast

This is the implementation of crrev.com/c/866721 for arm.
Drive-by change: I simplified the slot index calculation.
Original description:
At the moment the slot index is encoded in the opcode. This, however,
sets an upper limit the slot index which is lower than what we want to
have (i.e. < 512). With this change we pass the slot index as an
immediate operand, which does not impose limits on the value it
contains.

This is the implementation of crrev.com/c/766371 for arm64.
Original description:
Add the ability to return (multiple) return values on the stack:
- Extend stack frames with a new buffer region for return slots.
This region is located at the end of a caller's frame such that
its slots can be indexed as caller frame slots in a callee
(located beyond its parameters) and assigned return values.
- Adjust stack frame constructon and deconstruction accordingly.
- Extend linkage computation to support register plus stack returns.
- Reserve return slots in caller frame when respective calls occur.
- Introduce and generate architecture instructions ('peek') for
reading back results from return slots in the caller.
- Aggressive tests.
- Some minor clean-up.

https://github.com/tc39/ecma262/pull/988 gained concensus during the
september 2017 TC39 meetings. This moves the load of the "next" method
to the very beginning of the iteration protocol, rather than during
each iteration step.
This impacts:
- yield*
- for-of loops
- spread arguments
- array spreads
In the v8 implementation, this also affects async iteration versions of
these things (the sole exception being the Async-From-Sync iterator,
which requires a few more changes to work with this, likely done in a
followup patch).
This change introduces a new AST node, ResolvedProperty, which can be used
as a callee by Call nodes to produce the same bytecode as Property calls,
without observably re-loading the property. This is used in several
AST-desugarings involving the iteration protocol.

Before this, only the [[ProxyHandler]] was set to null during revocation
of the Proxy through either the v8::Proxy::Revoke() or the
Proxy.revocable() API. To be consistent with the spec, the Proxy's
target is set to null as well. This change should not be observable
through JS, since the check for if the Proxy is revoked should always
use the handler. But the changed value is exposed through the public
v8::Proxy::GetTarget() API, which is used by the inspector API and
Node.js.
Also included is a much more comprehensive test for Inspector's support
for Proxy, which prior to this commit did not work as intended.

Disallow using the PC as a base in LDR and instead provide a dedicated assembler
method for pc-relative loads. The reason for this is that the generic
`Assembler::ldr` method may decide to generate more instructions if the offset
is out of range, and if the PC was the base, we would get surprising
results. For example:
~~~
ldr r0, [pc, #0xcabba9e]
~~~
is not equivalent to:
~~~
movw ip, #0xba9e
movt ip, #0xcab
ldr r0, [pc, ip]
~~~
since the reference to the PC has moved down two instructions!
We could teach the assembler to handle those cases correctly, but pc-relative
loads are used in specific cases only so that's not necessary.
As a drive-by, remove a reference to code aging.
