8654df00f4 [heap] Skip some tests with --stress-concurrent-allocation
Tests do not expect concurrent allocation and are simply skipped in that
configuration.

faed29869f [nci] Change testing mode to --turbo-nci-as-midtier
To properly test tier-up in the V8 test suite, change the test variant
previously called --turbo-nci-as-highest-tier to
--turbo-nci-as-midtier.  As a midtier (between ignition and turbofan),
all major parts of the NCI pipeline (codegen, caching inside the same
native context, tier-up) are exercised by test suite.

764ee9bd92 [nci] Consume cached code
When creating a new JSFunction (either through Factory::NewFunction or
the FastNewClosure builtin), install the cached Code object if one
exists. In the former, this happens explicitly; in the former implicitly
through %CompileLazy.

Drive-by: Clean up nci tracing methods.
Drive-by: Rename maybe_has_... to may_have_cached_code.

f57ce0f4c8 [compiler] Ensure source positions collected when required
If source positions are not required when a background compilation task
starts, but then something like profiling is started before the task
finalizes, then logging of the compilation task will crash due to a
missing source position table.

This ensures source positions are collected if source positions are
required during finalization.

accepts two parameters: the initial and the maximum heap size.
Based on the given limits the function computes the default size
for the young and the old generation.

The patch also cleans up the existing functions to make them
consistent in terms of units and heap structure.

The "->" at the expression location was then rewritten to ".".

4b0f9c856e [cleanup] Use Vector::begin instead of Vector::start
Our {Vector} template provides both {start} and {begin} methods. They
return exactly the same value. Since the {begin} method is needed for
iteration, and is also what standard containers provide, this CL
switches all uses of the {start} method to use {begin} instead.

Patchset 1 was auto-generated by using this clang AST matcher:
    callExpr(
        callee(
          cxxMethodDecl(
            hasName("start"),
            ofClass(hasName("v8::internal::Vector")))
        ),
        argumentCountIs(0))

Patchset 2 was created by running clang-format. Patchset 3 then
removes the now unused {Vector::start} method.

75629d5f9a [turbofan] Skip arguments adaptor when target cannot observe arguments.
When calling a known function from optimized code, where the number of
actual arguments does not match the number of expected arguments,
TurboFan has to call indirectly via the arguments adaptor trampoline,
which creates an argument adaptor frame underneath the activation record
for the callee. This is done so that the callee can still get to the
actual arguments, using either

1. the arguments object, or
2. rest parameters (to get to superfluous arguments), or
3. the non-standard Function.arguments accessor (for sloppy mode
   functions), or
4. direct eval(), where we don't know whether there's a use of the
   arguments object hiding somewhere in the string.

However going through the arguments adaptor trampoline is quite
expensive usually, it seems to be responsible for over 60% of the
call overhead in those cases.

So this adds a fast path for the case of calling strict mode functions
where we have an arguments mismatch, but where we are sure that the
callee cannot observe the actual arguments. We use a bit on the
SharedFunctionInfo to indicate that this is safe, which is controlled
by hints from the Parser which knows whether the callee uses either
arguments object or rest parameters.

In those cases we use a direct call from optimized code, passing the
expected arguments instead of the actual arguments. This improves the
benchmark on the document below by around 60-65%, which is exactly
the overhead of the arguments adaptor trampoline that we save in this
case.

This also adds a runtime flag --fast_calls_with_arguments_mismatches,
which can be used to turn off the new behavior. This might be handy
for checking the performance impact via Finch.

592aeefa8d Defer inferring language mode as far as possible
Inferring the language mode involves iterating the stack to find the
closure. This is an expensive operation and should be done only when
required. This cl changes the implementation to infer the language
mode only when we can't defer it any further. Currently, we infer the
language mode when throwing an exception or when passing this
information to PropertyCallbackArguments.

This cl also changes the language mode parameter to SetProperty
related methods to Maybe<ShouldThrow>. We only use the language mode to
decide if we need to throw and using ShouldThrow instead of language
mode simplifies the code by avoiding conversions from Maybe<ShouldThrow>
to Maybe<LanguageMode> and vice-versa.

e2846ea6e4 Reland "Change SetProperty/SetSuperProperty to infer language mode when possible"
This is a reland of 0896599f6f with a fix for
failing layout test.

Original change's description:
> Change SetProperty/SetSuperProperty to infer language mode when possible
>
> In most cases, the language mode can be inferred from the closure and
> the context. Computing the language mode instead of passing it around
> simplifies the ICs and will make it possible to go towards lazily
> allocating feedback vectors. Currently ICs obtain the language mode from
> the feedback vectors and with lazy feedback allocation we may not always
> have feedback vectors. Since computing language mode is a bit expensive
> we want to defer it as far as possible.
>
> In Array builtins and other builtins like Reflect.Set we need to force a
> language mode when setting the properties. To support these cases the
> SetProperty methods allow the language mode to be overridden when needed.
>
> This is a first cl in a series of cls, that will defer the language mode
> computation further and remove language mode where it is not needed.

and adds a named constructor to make it explicit that an EnumSet should
be constructed from an integral value.
Also refactor the use in cctest.h to have less statically declared
constants. Instead, just create the set of extensions in the individual

0a7e08ef26 [compiler] finalize compile jobs asap when compiling on main thread
Previously, we finalize all compile jobs at once. This keeps the zone memory
in every compile job alive until the end. This contributes to a high peak
memory when many functions are compiled eagerly, for example when producing
cache data for the ServiceWorker cache.

Memory tracked by the AccountingAllocator in bytes, prior to this change in
the test case:
peak memory after init:              8192
peak memory after lazy compile:     41200
peak memory after lazy compile:     41200
peak memory after eager compile:   164256

With this change, if we are compiling on the main thread, we finalize every
compile job as soon as it is done and dispose the compile job and its zone
memory.

After this change:
peak memory after init:              8192
peak memory after lazy compile:     41200
peak memory after lazy compile:     41200
peak memory after eager compile:    41376
