This was introduced due to a false positive by the linter script. We
have blacklisted the "build/include_what_you_use" linter bucket in our
presubmit.py wrapper for that reason.

ECMAScript dates act as if the Gregorian changeover happened at the
beginning of time. This patch fixes up internationalized date
formatting to set that changeover properly, as opposed to the ICU
default which is in the 16th century.

Deoptimization expects the context and function marker on the stack.
To let the register allocator control spilling of the live ranges
corresponding to these 2 operands, we need their use to be represented
accurately.

Port 95844d94f3
Original commit message:
The new operator provides a second output which indicates whether the
conversion from float64 to int64 was successful or not. The second
output returns 0 if the conversion fails. If the conversion succeeds,
then the second output is differs from 0.
The second output can be ignored, which means that the operator can be
used the same way as the original operator.
I implemented the new operator on x64 and arm64. @v8-mips-ports and
@v8-ppc-ports, can you please take care of the mips64 and ppc64
implementation of the second output?

This adds a runtime flag that controls whether the WASM object is
exposed to JavaScript. While currently guarded by the V8_WASM build-time
flag, after landing in V8 the build-time flag will be removed, leaving
only this new runtime flag.

This patch improves escape analysis and fixes bugs
triggered by clusterfuzz. Impovements include:
* Handling of LoadElement/StoreElement if index is a
constant
* Handling of JSStoreProperty: invalidate all information,
as the store could have altered any field.
* Treat phis that use an allocation as escaping
* Improve resolution of replacements

This makes the strong link from optimized code to code objects for all
inlined functions explicit. It adds direct references to code objects
into deoptimization data as literals. Note that this is not necessarily
the code that will be deoptimized to, because the code on the shared
function info might be replaced by other components (e.g. debugger).
Those replacement code objects however are all non-flushable, marking
explicit strong links for reachability unnecessary.

The JSInliningHeuristic keeps a list of nodes, which might have been
killed by other reducers before the JSInliningHeuristic looks at it
again, so it has to check whether nodes are dead before trying to
expand them later (this is similar to what the ValueNumberingReducer
needs to do with its internal table).

- Add JSReceiver::SetIntegrityLevel, with a fast path for regular objects.
- Make Object.{freeze,seal} call this via %Object{Freeze,Seal}, thus no longer
using broken or deprecated functions from v8natives.js.
- Add JSReceiver::OwnPropertyKeys convenience function.
- Reenable harmony/proxies-hash.js test.

There's no benefit in embedding the context as a constant for direct
calls. In fact it seems to be cheaper both size and execution wise to
just always load the context from the target.
