b79d7b0486 [x64] Zero/sign-extend loads to 64-bit registers.
Before this change we would first load an 8/16/32-bit value from memory into a 32-bit register, then zero/sign-extend from that register to a 64-bit one. Now we replace that pattern with a single movsx/movzx.

4df91581d1 [modules] Introduce new VariableLocation for module imports/exports.
Introduces a new VariableLocation MODULE for variables that live in a
module's export table.  Scope analysis sets this for the approriate variables.
Not yet supported by any backend.

Also, treats all imports as CONST bindings (including namespace imports), rather
than having new special variable modes.

0c699a5819 Don't analyze scopes outside of the compiled scope
The outer scope of the scope we are compiling doesn't need analysis. Either we're compiling top-level code in which case there is no outer scope. Or we are compiling code at the top-level (eval, function, module), and there won't be anything to resolve in the outer scope. Lastly we could also be compiling with a deserialized scope. In that case the outer scope is already resolved.

e6822a8338 [turbofan] Add initial support for growing stores.
Introduce a dedicated MaybeGrowFastElements simplified operator, which
tries to grow a fast elements backing store for a given element that
should be added to an array/object. Use that to lower a growing keyed
store to a sequence of

 1) check index is a valid array index,
 2) check stored value,
 3) maybe grow elements backing store (and deoptimize if it would
    normalize), and
 4) store the actual element.

The actual growing is done by two dedicated GrowFastDoubleElements
and GrowFastSmiOrObjectElements builtins, which are very similar to
the GrowArrayElementsStub that is used by Crankshaft.

Drive-by-fix: Turn CopyFixedArray into CopyFastSmiOrObjectElements
builtin, similar to the new growing builtins, so we don't need to
inline the store+write barrier for the elements into all optimized
code objects anymore.

Also fix a bug in the OperationTyper for NumberSilenceNaN, which was
triggered by this change.

Up until now "-0.0 - x" was lowered in the instruction selector. I moved
the lowering now to the MachineOperatorReducer.

I did not remove the lowering from the instruction selector yet, I would

6768456db5 Use Variable::binding_needs_init() to determine hole initialization
The old code was using VariableMode, but that signal is both
over-pessimistic (some CONST and LET variables need no hole-initialization)
and inconsistent with other uses of the InitializationFlag enum (such
as %LoadLookupSlot).

This changes no observable behavior, but removes unnecessary hole
initialization and hole checks in a few places, including
block-scoped function declarations, super property lookups,
and new.target.

e144335fe3 [turbofan] Insert sigma nodes for loop variable backedge.
If we infer loop variable bounds, we need to insert a type rename node
(sigma) to make sure that simplified lowering can choose representations
consistently.

> Before this change we would first load an 8/16/32-bit value from memory into a 32-bit register, then zero/sign-extend from that register to a 64-bit one. Now we replace that pattern with a single movsx/movzx.

f68059b73a [x64][ia32] Add Support for the Float64Neg and Float32Neg turbofan operators.
Benedikt, do you think we could also provide these operators on mips,
maybe by expanding them to "-0.0 -x"? If mips can provide these operators,
then we could make Float64Neg and Float32Neg real operators and not just
OptionalOperators.
