84cfc9ca71 [ic] KeyedLoadIC error on strings with negative indexes
We need to check if the index is less than zero and miss to the runtime
if this is so.

713ebae3b4 [class] Add IC support for defining class fields to replace runtime call
Introduces several new runtime mechanics for defining private fields,
including:
  - Bytecode StaKeyedPropertyAsDefine
  - Builtins StoreOwnIC{Trampoline|Baseline|_NoFeedback}
  - Builtins KeyedDefineOwnIC{Trampoline|Baseline|_Megamorphic}
  - TurboFan IR opcode JSDefineProperty

These new operations can reduce a runtime call per class field into a
more traditional Store equivalent. In the microbenchmarks, this
results in a substantial win over the status quo (~8x benchmark score
for single fields with the changes, ~20x with multiple fields).

The TurboFan JSDefineProperty op is lowered in
JSNativeContextSpecialization, however this required some hacks.
Because private fields are defined as DONT_ENUM when added to the
object, we can't find a suitable transition using the typical data
property (NONE) flags. I've added a mechanism to specify the required
PropertyAttributes for the transition we want to look up.

Details:

New bytecodes:
  - StaKeyedPropertyAsDefine, which is essentially StaKeyedProperty
    but with a different IC builtin (KeyedDefineOwnIC). This is a
    bytecode rather than a flag for the existing StaKeyedProperty in
    order to avoid impacting typical keyed stores in any way due to
    additional branching and testing.

New builtins:
  - StoreOwnIC{TTrampoline|Baseline|_NoFeedback} is now used for
    StaNamedOwnProperty. Unlike the regular StoreIC, this variant will
    no longer look up the property name in the prototype.
    In adddition, this CL changes an assumption that
    StoreNamedOwnProperty can't result in a map transition, as we
    can't rely on the property already being present in the Map due
    to an object literal boilerplate.

    In the context of class features, this replaces the runtime
    function %CreateDataProperty().

  - KeyedDefineOwnIC{Trampoline|Baseline|_Megamorphic} is used by the
    new StaKeyedPropertyAsDefine bytecode. This is similar to an
    ordinary KeyedStoreIC, but will not check the prototype for
    setters, and for private fields, will take the slow path if the
    field already exists.

    In the context of class features, this replaces the runtime
    function %AddPrivateField().

TurboFan IR:
  - JSDefineProperty is introduced to represent a situation where we
    need to use "Define" semantics, in particular, it codifies that we
    do not consult the prototype chain, and the semantics relating to
    private fields are implied as well.

2cbcf6e089 [wasm] Remove process-wide address space limit
The address space limit puts an arbitrary cap on the total reservation
size, thus limiting the total number of Wasm memories to around 100 on
64-bit systems.
Since the usable address space on 64 bit is much larger than the
1TB+4GB limit, this makes us reject code that we could otherwise just
execute.

This CL thus removes that limit completely.

considerations.

This fixes a long-standing TODO to disallow importing receivers that
have "toString" or "valueOf" patched. Calling those methods could have
observable side effects, so allowing that would require bigger
refactorings to ensure that we only call each such function exactly once
per import, and in the right order.
Since this use case is rare, we just forbid importing such receivers.

7d849870ff [regexp] Reorganize and deduplicate in the regexp parser
The parser is organized in a somewhat tricky way s.t. it can be
hard to map the implementation back to the specified grammar.

In particular, the logic for CharacterClassEscape, ClassEscape,
and CharacterEscape was implemented twice - once inside a character
class, once outside.

This CL refactors related logic to have only a single implementation.

As a drive-by, fix one related inconsistency related to \k inside
a character class.

cd77eb7bd7 [builtins] Fixes TypedArray ops behavior when the buffer was detached
After the parameter processing, the arraybuffer may have been detached.
TypedArray copyWithin/fill should throw in that condition. TypedArray
includes should return false if the search element is not undefined.

732d09a63b [runtime] Fix object cloning with spreads
When cloning objects using spread and update properties (e.g.
obj = {...o, x: 0}), we wrongly used the setter for the update argument
if one was set.
This CL changes the behaviour such that all arguments following the
spread are treated as dynamic arguments.

a0ace8a8a5 [wasm] Interpret table.grow result as 32 bit
In Liftoff, the result of table.grow was smi-untagged and sign-extended
to a ptr-sized value. However the result is typed as i32, so the upper
32 bits should be cleared on 64 bit platforms. In particular this is
observable when the value is used as an index for a memory operand,
which leads to the repro in the attached issue.

Match the TF behavior by untagging the value as a 32-bit int.
