introduced in https://crrev.com/72f884a19fa4434bba6fc0e013ec4ea0a2366893

The regression comes from adding the next weak field of AllocationSite
as a hidden reference into the snapshot.

Before 72f884 the reference was implicitly ignored because the body
descriptor of AllocationSite did not include it.

This patch explicitly skip the next weak field of AllocationSite.

This makes the debug-only scope-name actually debug-only-allocated, replaces num_vars_ usages by variables_.occupancy, and shuffles fields around in the scope class for better packing.

This reduces sizeof(i::Scope) from 360 to 328 bytes on x64.

This switches our inlining tests (i.e. cctest/test-run-inlining) to rely
on global object instead of function context specialization, which is
more in sync with what we are actually shipping. It will also allow us
to test inlining with the BytecodeGraphBuilder without having to add
support for function context specialization just for testing purposes.

The flag was introduced for ignition development. It can only
be used when running ignition tests in isolation on the bots.

The bots only use ignition_turbo in isolation since a while
and don't pass the --ignition flag anymore.

This CL fixes a long-standing bug with Object.keys where the enumerability
check was omitted if the [ownKeys] trap is not present. The only distinction the
KeyAccumulator needs is whether it collects keys for for-in (is_for_in_) or not.
ForInFilter performs a separate step to filter out non-enumerable keys later-on
while in all the other use-cases we have to filter keys.

This is another step towards lazily allocating them in the block state.
ClassLiteral should also have a lazy block-scope for the outermost scope,
but currently that doesn't work due to the parameter initializer rewriter
and minor implementation details in ignition and turbofan.

This removes the frame state input representing the before-state from
nodes having any shift operator. Any lowering that woult insert number
conversions of the inputs has already been disabled when deoptimization
is enabled, because the frame state layout is no longer known.

Rather than finalizing after rewriting do-expressions, we rewrite in the
outer scope if the block scope was finalized. Rewriting do expressions
cannot introduce any new nodes that requires the block to stay around,
so finalizing before and after is equivalent. (Only a temporary is
introduced which always ends up in a ClosureScope)

Allow inlining of getters and setters into TurboFan optimized code.
This just adds the basic machinery required to essentially inline
the setter and getter dispatch code for the (keyed) load/store ICs.
There'll be follow up CLs to also actually inline some of the interesting
accessor functions itself, like the byteLength and friends for the
TypedArrays.

This introduces a bunch of new tests that test various aspects of
accessor inlining in TurboFan (without the actual inlining), and does
the appropriate fixes to the AstGraphBuilder. The actual inlining CL
will land separately (so we don't need to revert the tests and fixes
if the accessor CL has to be reverted).

We have a similar optimization for unchecked integer modulus, which
already boosted some asm.js use cases. Now this optimization is almost
as effcient as Crankshafts known power of 2 right hand side optimization
for modulus, but it can still deal with any rhs (except 0), and doesn't
require the interpreter to also collect known power of two rhs feedback.
