b7dc9915ff [regexp] Only emit valid ranges in MakeRangeArray
Character class handling in the irregexp pipeline is quite complex;
codepoints outside the BMP (basic multilingual plane) are only
translated into surrogate pairs when needed, e.g. when the subject
string is two-byte. If not needed, the codepoints simply stay part of
the list of CharacterRanges.

In EmitCharClass, we determine the valid subset of ranges through
ranges_length; until this CL, we forgot to pass that information on to
MakeRangeArray. Do that now by truncating the list of CharacterRanges.

d757cd5c63 [compiler] Fix mid-tier register allocator issue
If an output operand has "same as input" policy, we cannot assume that
it's input 0. Instead we should look at the {input_index}.

The bug manifests on Wasm select instructions, where the input index is
actually 2 and not 0.

In order to test this better, we introduce the a new
--turbo-force-mid-tier-regalloc flag, which always uses the mid-tier
register allocator. Otherwise the bug would only manifest on huge
functions.

88c0f72927 [turbofan] Fix calling class constructors with spread
Calling class constructors without new is a spec violation and should
raise an exception.
In [1] calling class constructors with spread (without new) was handled
by reducing the node to a call to runtime to raise the exception.
However, arguments of the call have to be evaluated first ([2]).
This CL changes the reduction of JSCallWithSpread/JSCallWithArrayLike to
a no-op in JSCallReducer if the target is a class constructor, delaying
raising of the exception to the call builtin.

e127f58410 [turbofan] Handle class constructor
Handling of class constructors was moved from CallFunction to Call
in [1].
When reducing calls with spread we forward varargs directly to
CallFunction, if we are spreading to inlined arguments or arguments of
the outermost function.
In that case we didn't check for class constructors and therefore didn't
raise an exception.
This CL adds checks for class constructors to all JSCall* nodes in
JSCallReducer that missed them before.

70a0baaa59 [test] Robustify wait in regress-bug-9161
mjsunit/regress/regress-crbug-9161 had two spinlocks on an atomic:

  1. WaitUntil(lock == kStageRunning)
  2. WaitUntil(lock == kStageDone)

But, in theory the worker updating the "lock" could progress all the way
to kStageDone before the first loop manages to check the lock value
again.

We can make this more robust by checking:

  1. WaitUntil(lock != kStageInit)
  2. WaitUntil(lock == kStageDone)

That way both loops check for _any_ state past the state they want to
progress past.

bce4410837 [wasm][turbofan] Improve inlining heuristics
This CL improves wasm inlining heuristics in Turbofan, for an average
8,5% performance improvement in selected benchmarks.

Changes:
- In WasmInliner::Reduce(), only collect inlining candidates into a
  priority queue, according to WasmInliner::LexicographicOrdering.
  Move actual inlining to Finalize().
- Remove the InlineFirstFew heuristic. Add two limits to inlining:
  Maximum relative size increase (reversely proportional to the function
  size), and absolute size increase.
- Pass information about call frequency from liftoff-collected feedback
  to the WasmInliner though the wasm module.
- Run wasm inlining along other optimizations in the pipeline.
- Split inlining and speculative inlining tests.

  - 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.

The address space limit puts an arbitrary cap on the total reservation

Since the usable address space on 64 bit is much larger than the

Since this use case is rare, we just forbid importing such receivers.

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.
