d89d185fad [fastcall] expose wasm memory to cfunction
Load current Memory start/size off of the wasm instance when entering
fast calls, so they can use that info for whatever they need to do.
Fast calls from JS set the memory to null, and the memory does not
need to be piped from wasm to slow callbacks as wasm always calls
the fast function.

4c81827c8d optimize Set#has
Code for map methods was added a really long time ago but no one ever
brought that to set. Adds new common lowering for both collections and
updates the SetPrototypeHas builtin. My initial testing shows this to
be as much as 50x faster in some cases.

d7bd292628 [fastcall] combine wasm and js fast call builder
A lot of logic is missing from the Wasm entry for fast api calls.
The majority of the lowering is shared between wasm and js, and uses
the same graph operators, so this adds a common fast api call builder
which can be called from the wasm compiler and the js compiler.

c2d239ddb3 Reland "[compiler] Remove the optimized OSR code if deoptimizing at inside of loop"
This is a reland of commit c8c176190a

This CL includes:

- crrev.com/c/3679846 Add condition use_ic to the removing the optimized OSR code logic
- crrev.com/c/3686589 Add out of bytecode array to break condition of removing OSR code cache logic
- Add JumpLoop nesting level 0 to break condition of removing OSR code cache logic
- Change to use Deoptimizer::DeoptimizeFunction() to deoptimize OSR code

Original change's description:
> [compiler] Remove the optimized OSR code if deoptimizing at inside of loop
>
> If the optimized code is deoptimized and the deoptimized exit offset is
> inside of the optimized OSR code related loop, the optimized OSR code is

> optimized OSR code and soon later deoptimization of the optimized OSR
> code.
> This CL will reduce deoptimization. E.g. Deoptimization of JetStream2
> case navier-stokes function addFields is reduced from twice to once.

fce1047f00 Reland "[interpreter] Optimize strict equal boolean"
This is a reland of commit 62632c0805.
Reason for previous revert: Performance regressions crbug.com/1315724.
The reland only optimizes strict equal boolean literal like "a===true"
or "a===false", and we generate TestReferenceEqual rather than
TestStrictEqual for the comparasion. And also add typed optimization
for ReferenceEqual when all inputs are boolean with boolean constant.

Original change's description:

87d73a3ae0 Reland "[turbofan] Enable --verify-simplified-lowering in debug"
This reverts commit aaedd8b788.

Changes in the reland:
The inital problem was caused by nodes that were removed during SL
because they are no-ops but have an effect on typing (in the repro, this
was e.g. PlainPrimitiveToNumber). The reland introdocues a new operator
SLVerifierHint that is used exclusively in SL to provide hints to the
verifier and that solves this problem. SLVerifierHint also replaces the
previous use of TypeGuard to type constant nodes for the verifier.

0d1ffe30f8 [ic] name Set/Define/Store property operations more consistently
For background and reasoning, see
https://docs.google.com/document/d/1jvSEvXFHRkxg4JX-j6ho3nRqAF8vZI2Ai7RI8AY54gM/edit
This is the first step towards pulling the DefineNamedOwn operation out
of StoreIC.

Summary of the renamed identifiers:

Bytecodes:

- StaNamedProperty -> SetNamedProperty: calls StoreIC and emitted for
  normal named property sets like obj.x = 1.
- StaNamedOwnProperty -> DefineNamedOwnProperty: calls
  DefineNamedOwnIC (previously StoreOwnIC), and emitted for
  initialization of named properties in object literals and named
  public class fields.
- StaKeyedProperty -> SetKeyedProperty: calls KeyedStoreIC and emitted
  for keyed property sets like obj[x] = 1.
- StaKeyedPropertyAsDefine -> DefineKeyedOwnProperty: calls
  DefineKeyedOwnIC (previously KeyedDefineOwnIC) and emitted for
  initialization of private class fields and computed public class
  fields.
- StaDataPropertyInLiteral -> DefineKeyedOwnPropertyInLiteral: calls
  DefineKeyedOwnPropertyInLiteral runtime function (previously
  DefineDataPropertyInLiteral) and emitted for initialization of keyed
  properties in object literals and static class initializers. (note
  that previously the StoreDataPropertyInLiteral runtime function name
  was taken by object spreads and array literal creation instead)
- LdaKeyedProperty -> GetKeyedProperty, LdaNamedProperty ->
  GetNamedProperty, LdaNamedPropertyFromSuper ->
  GetNamedPropertyFromSuper: we drop the Sta prefix for the property
  store operations since the accumulator use is implicit and to make
  the wording more natural, for symmetry the Lda prefix for the
  property load operations is also dropped.

opcodes:

- (JS)StoreNamed -> (JS)SetNamedProperty: implements set semantics for
  named properties, compiled from SetNamedProperty (previously
  StaNamedProperty) and lowers to StoreIC or Runtime::kSetNamedProperty
- (JS)StoreNamedOwn -> (JS)DefineNamedOwnProperty: implements define
  semantics for initializing named own properties in object literal and
  public class fields, compiled from DefineNamedOwnProperty (previously
  StaNamedOwnProperty) and lowers to DefineNamedOwnIC
  (previously StoreOwnIC)
- (JS)StoreProperty -> (JS)SetKeyedProperty: implements set semantics
  for keyed properties, only compiled from SetKeyedProperty(previously
  StaKeyedProperty) and lowers to KeyedStoreIC
- (JS)DefineProperty -> (JS)DefineKeyedOwnProperty: implements define
  semantics for initialization of private class fields and computed
  public class fields, compiled from DefineKeyedOwnProperty (previously
  StaKeyedPropertyAsDefine) and calls DefineKeyedOwnIC (previously
  KeyedDefineOwnIC).
- (JS)StoreDataPropertyInLiteral ->
  (JS)DefineKeyedOwnPropertyInLiteral: implements define semantics for
  initialization of keyed properties in object literals and static
  class initializers, compiled from DefineKeyedOwnPropertyInLiteral
  (previously StaDataPropertyInLiteral) and calls the
  DefineKeyedOwnPropertyInLiteral runtime function (previously
  DefineDataPropertyInLiteral).

Runtime:
- DefineDataPropertyInLiteral -> DefineKeyedOwnPropertyInLiteral:
  following the bytecode/opcodes change, this is used by
  DefineKeyedOwnPropertyInLiteral (previously StaDataPropertyInLiteral)
  for object and class literal initialization.
- StoreDataPropertyInLiteral -> DefineKeyedOwnPropertyInLiteral_Simple:
  it's just a simplified version of DefineDataPropertyInLiteral that
  does not update feedback or perform function name configuration.
  This is used by object spread and array literal creation. Since we
  are renaming DefineDataPropertyInLiteral to
  DefineKeyedOwnPropertyInLiteral, rename this simplified version with
  a `_Simple` suffix. We can consider merging it into
  DefineKeyedOwnPropertyInLiteral in the future. See
  https://docs.google.com/document/d/1jvSEvXFHRkxg4JX-j6ho3nRqAF8vZI2Ai7RI8AY54gM/edit?disco=AAAAQQIz6mU
- Other changes following the bytecode/IR changes

IC:

- StoreOwn -> DefineNamedOwn: used for initialization of named
  properties in object literals and named public class fields.
  - StoreOwnIC -> DefineNamedOwnIC
  - StoreMode::kStoreOwn -> StoreMode::kDefineNamedOwn
  - StoreICMode::kStoreOwn -> StoreICMode::kDefineNamedOwn
  - IsStoreOwn() -> IsDefineNamedOwn()
- DefineOwn -> DefineKeyedOwn: IsDefineOwnIC() was already just
  IsDefineKeyedOwnIC(), and IsAnyDefineOwn() includes both named and
  keyed defines so we don't need an extra generic predicate.
  - StoreMode::kDefineOwn -> StoreMode::kDefineKeyedOwn
  - StoreICMode::kDefineOwn -> StoreICMode::kDefineKeyedOwn
  - IsDefineOwn() -> IsDefineKeyedOwn()
  - IsDefineOwnIC() -> IsDefineKeyedOwnIC()
  - Removing IsKeyedDefineOwnIC() as its now a duplicate of
    IsDefineKeyedOwnIC()
- KeyedDefineOwnIC -> DefineKeyedOwnIC,
  KeyedDefineOwnGenericGenerator() -> DefineKeyedOwnGenericGenerator:
  make the ordering of terms more consistent
- IsAnyStoreOwn() -> IsAnyDefineOwn(): this includes the renamed and
  DefineNamedOwn and DefineKeyedOwn. Also is_any_store_own() is
  removed since it's just a duplicate of this.
- IsKeyedStoreOwn() -> IsDefineNamedOwn(): it's unclear where the
  "keyed" part came from, but it's only used when DefineNamedOwnIC
  (previously StoreOwnIC) reuses KeyedStoreIC, so rename it accordingly

Interpreter & compiler:
- BytecodeArrayBuilder: following bytecode changes
    - StoreNamedProperty -> SetNamedProperty
  - StoreNamedOwnProperty -> DefineNamedOwnProperty
  - StoreKeyedProperty -> SetKeyedProperty
  - DefineKeyedProperty -> DefineKeyedOwnProperty
  - StoreDataPropertyInLiteral -> DefineKeyedOwnPropertyInLiteral
- FeedbackSlotKind:
  - kDefineOwnKeyed -> kDefineKeyedOwn: make the ordering of terms more
    consistent
  - kStoreOwnNamed -> kDefineNamedOwn: following the IC change
  - kStoreNamed{Sloppy|Strict} -> kSetNamed{Sloppy|Strict}: only
    used in StoreIC for set semantics
  - kStoreKeyed{Sloppy|Strict} -> kSetKeyed{Sloppy|Strict}: only used
    in KeyedStoreIC for set semantics
  - kStoreDataPropertyInLiteral -> kDefineKeyedOwnPropertyInLiteral:
    following the IC change
- BytecodeGraphBuilder
  - StoreMode::kNormal, kOwn -> NamedStoreMode::kSet, kDefineOwn: this
    is only used by BytecodeGraphBuilder::BuildNamedStore() to tell the
    difference between SetNamedProperty and DefineNamedOwnProperty
    operations.

Not changed:

- StoreIC and KeyedStoreIC currently contain mixed logic for both Set
  and Define operations, and the paths are controlled by feedback. The
  plan is to refactor the hierarchy like this:
  ```
  - StoreIC
    - DefineNamedOwnIC
    - SetNamedIC (there could also be a NamedStoreIC if that's helpful)
    - KeyedStoreIC
      - SetKeyedIC
      - DefineKeyedOwnIC
      - DefineKeyedOwnICLiteral (could be merged into DefineKeyedOwnIC)
      - StoreInArrayLiteralIC
    - ...
  ```
  StoreIC and KeyedStoreIC would then contain helpers shared by their
  subclasses, therefore it still makes sense to keep the word "Store"
  in their names since they would be generic base classes for both set
  and define operations.
- The Lda and Sta prefixes of bytecodes not involving object properties
  (e.g. Ldar, Star, LdaZero) are kept, since this patch focuses on
  property operations, and distinction between Set and Define might be
  less relevant or nonexistent for bytecodes not involving object
  properties. We could consider rename some of them in future patches
  if that's helpful though.

8264058c28 [test] Add gc-interval flag to deopt-pretenure test
mjsunit/compiler/deopt-pretenure.js is flaky due to --gc-interval in
some variants.
The flag can cause a variable to be promoted to old space before the
test can force allocation site pretenuring for that variable, which is
essential for the test case.

d19a707d14 [compiler] Fix typing JSLoadNamed of private brands
Private method loads are compiled to a named load of a private brand,
which always loads a BlockContext. This BlockContext holds the private
methods common to all instances of a class. TurboFan currently considers
JSLoadNamed to be of Type::NonInternal(). Private methods break this
assumption, since BlockContext is of Type::OtherInternal().

This CL changes the typing of JSLoadNamed of private brands to be
Type::OtherInternal().

- Add new test

This CL adds the following specific cases, to make sure they are
correctly handled by the slow path:
 - the backing store of a TypedArray gets detached after optimisation
 - passing null instead of a TA doesn't lead to a deopt

7cdf4c69b0 Fix flakes in store-data-property-in-literal-private.js
In stress runs a GC may kick in before assertOptimized() is called
on the optimized function, causing it to deoptimize and the test
would fail even if the function is optimized as expected.
Adding --no-stress-flush-code --no-flush-bytecode fixes the timing
issue.

45227ffdb4 [turbofan] extend type asserts to cover all JS types
Extend type assertions to all types covering JavaScript values.
This is achieved by allocating type representations on the heap using
newly defined HeapObject subclasses. To allocate these in the compiler,
we disable concurrent compilation for the --assert-types flag for now.

Fix two type errors that came up with the existing tests:
1. JSCreateKeyValueArray has type Array (i.e., a JSArray) instead of
   OtherObject.
2. OperationTyper::NumberToString(Type) can type the result as the
   HeapConstant Factory::zero_string(). However, NumberToString does
   not always produce this string. To avoid regressions, the CL keeps
   the HeapConstant type and changes the runtime and builtin code to
   always produce the canonical "0" string.

A few tests were failing because they check for truncations to work
and prevent deoptimization. However, AssertType nodes destroy all
truncations (which is by design), so these tests are incompatible
and now disabled for the assert_types variant.

Drive-by fix: a few minor Torque issues that came up.

e1f5e68ebb [fastcall] Fix MachineType for FP TypedArray arguments
This CL fixes an issue in EffectControlLinearizer, where the primitive
type of the argument of a fast C call was used to compute its
MachineType even when the argument was actually a TypedArray, which
should always be treated as a Tagged type. This resulted in Float32/64
typed arrays being passed in FP registers, leading to a crash in the
register allocator.

Drive-by fix: Fixed output from --trace-turbo-alloc so that all of its
sub-parts are printed with PrintF, avoiding interleaved log lines.
