This operator now provides a second output which indicates whether the conversion from float64 to uint64 was successful or not. The second output returns 0 if the conversion fails, or something else if the conversion succeeds.
The second output can be ignored, which means that the operator can be used the same as the original operator.
I implement 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?

The new minorGC pass collects all unmodified objects that are not marked
active by blink. The earlier implementation assumed all new space nodes
to be Heap objects. Updated this code to handle Smi objects as well.

PreviousBytecodeHelper used to return Bytecode::kLast if the previous bytecode was not
in the same basicblock. Changed it to be instantiated only when the previous bytecode
is in the same basic block.

It's expensive to walk all shared function infos during the gc atomic
pause. Instead, use WeakCells to implement this structure without
manual clearing.
Reland due to a bug when reusing entries in the optimized code map.

This only introduces the basic support for both SOFT and EAGER deopts in
TurboFan, but doesn't make use of SOFT deopts anywhere yet (there are
some other issues blocking that). Basically every Deoptimize operator
now has a DeoptimizeKind, which can be either kSoft or kEager.

I noticed that using --print-opt-code was producing output unreliably.
Upon investigation, it turns out OFStream's destructor was not marked
virtual. Fixing this fixes the problem, as ostream flushes at destruction.

Reconstructing which stdlib object is used within an asm.js
module seems wasteful, given the typer has already checked this.
Preserving this information in a form that can be queried in
the asm-wasm-builder which generating code.

Instead of iterating the whole map space to find dead transitions,
look in weak cell list and transition array list.
Simple transitions are in the weak cell list.
Full transitions are in the transitions array list.

ECMAScript dates act as if the Gregorian changeover happened at the

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.

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
