This enables linter checking for "runtime/threadsafe_fn" violations
during presubmit and instead marks the few known exceptions that we

mdb_v8, a post-mortem debugger for Node.js, now uses JSArrayBuffer's
backing_store property and JSArrayBufferView's byte_offset property to
get access to the content of Buffer instances in node (which are
Uint8Array instances). This change adds post-mortem metadata for these
two properties.
This change also fixes a typo in
inobject_properties_of_constructor_function_index_offset that was added
to gen-postmortem-metadata in a previous change. It should be named
inobject_properties_or_constructor_function_index instead.

Original issue's description:
> Remove register index/code indirection
>
> Previous to this patch, both the lithium and TurboFan register
> allocators tracked allocated registers by "indices", rather than
> the register codes used elsewhere in the runtime. This patch
> ensures that codes are used everywhere, and in the process cleans

>
> Some highlights of changes:
>
> * TurboFan's RegisterConfiguration class moved to V8's top level
> so that it can be shared with Crankshaft.
> * Various "ToAllocationIndex" and related methods removed.
> * Code that can be easily shared between Register classes on
> different platforms is now shared.
> * The list of allocatable registers on each platform is declared

We not keep track of the histogram as we process values and do not wait until
printing the histogram. Furthermore processing the histogram is not O(n) for n
values.

mdb_v8, a post-mortem debugging tool for Node.js, allows users to
inspect ScopeInfo structures in order to get more information about
closures.
Currently, it hardcodes the metadata it uses to find this information.
This change allows it to get this metadata from the node binary itself,
and thus to adapt to future changes made to the layout of the ScopeInfo
data structure.

Since https://codereview.chromium.org/272163002, BitField3 is a raw
uint32 field, and not a SMI anymore.
Update tools/gen-postmortem-metadata.py so that post-mortem tools can
work with versions of V8 that shipped after that change.
This change was merged in github.com/joyent/node right before node
v0.12.0 was released.

Now run-tests.py understands "suite/foo/bar" with forward slashes for
command-line test selection on all test suites on all platforms.
Previously, file-based suites like mjsunit also accepted "mjsunit/foo\bar";
that behavior is sacrificed here in favor of unification. For the cctest
suite, OTOH, it wasn't possible on Windows to select specific tests at all.

Replace the ADD, SUB, etc. builtins with proper runtime implementations,
and expose them as runtime calls that can be used by the code stubs and
the interpreter (for now).
Also remove all the support runtime functions for ADD, SUB and friends,
namely %NumberAdd, %NumberSub, and so on.

- Modify js2c to accept --js and --nojs,
- modify mksnapshot to accept --startup_src
(instead of a positional parameter, so that it can be omitted),
- modify v8.gyp to use the above so that no target has multiple
output dependencies, and
- update GN to use the switches above.
(I have not succeeded in fixing the GYP->make translator to properly map
multi-output rules, so that they work as expected in all edge cases.
This CL signals defeat on that front, and instead I rewrite the GYP
file to avoid that situation in the first place.)

{AtomicValue}: A simple integer value that can be atomically
read/set/incremented.
{AtomicEnumSet}: Similar to EnumSet this set basically represents an atomic
bitfield based on enums. Atomic operations guarantee that setting one bit does
not race with setting other bits.
{AtomicEnumFlag}: A flag that is based on an enum that can be read and
(attempted to be) changed atomically.
