a0c2b7f2ad [Turbofan] Inline only if the candidate doesn't use all the available budget.
Inline only if there is some additional budget left even after inlining
the current candidate. This allows any small functions exposed by this
function to be inlined. Earlier we used to check for the limit after
inlining the function.

493a7d6475 [TurboFan] Delete AstGraphBuilder.
Deletes AstGraphBuilder and associated classes now that it is
unreachable. The following classes are also removed:
 - ControlBuilders
 - JSFrameSpecialization
 - AstLoopAssignmentAnalysis

Also removes flags from compilation-info which are no longer used, and removes
the no-deoptimization paths from TypedOptimization, JsTypedLowering,
JSIntrinsicLowering and JSBuiltinLowering.

dadbde038d [profview] Distinguish between parse/opt/unopt compile
Rather than lumping in parsing, bytecode compilation and optimized
compilation all into the same VM "compile" state, seperate them out
into individual states.  Additionally, add support for these states
to tickprocessor and profview.

cf4adddbfa [inspector] forEachSession iterates in predictable order
protocol::HashMap(std::unordered_map)::iterator doesn't provide any
guarantees about iteration order. At least Visual C++ from vS 2015 and
clang compile for loop inside forEachSession differently.
For tests we need stable order of iteration, so let's use std::map
instead.

1ca0eea23c [wasm] Correctly reconstitute ModuleEnv from runtime data

ModuleEnv accurately. Besides addressing a bug, this change
also does away with the need to relocate memory and globals
parameters (in lazy compilation), by using "the right ones" upfront.

Cleans up ast-numbering, runtime-profiler and some runtime functions to
remove now dead code.

This makes Full-codegen and AstGraphBuilder dead, but doesn't remove their
code yet, that will be done in a followup CL to keep things reviewable.

d09f9c424f [runtime] Do not clear prototype map descriptors.
Mutating the descriptor array and the layout descriptor of a map
races with the concurrent marking. This patch simply transfers
ownership of the descriptor array without mutating the map.

Since the old map is not going to be used anymore and there are
not transitions from the old map, this should be safe for trimming
the descriptor arrays during GC.

This patch also adds checks in IC code avoid caching of dummy
transitions from the abandoned prototype map.

80423e89b1 [test] Use glob expansion in test selection
The run_test.py tool test selection only expands asterisks at the end of
the test name. This CL introduces glob expansion in test selection
(asterisks are expanded anywhere in the path).

This is useful when tests that belong to the same area have different
prefixes. For example wasm cctests have two different prefixes:
'cctest/test-run-wasm*' and 'cctest/test-wasm*'. With this CL it is
possible to specify the selector 'cctest/*wasm*' to run them all.

293283d559 [builtins] Fix no elements check on the prototype chain.
Invoking Object.freeze on either the Object.prototype or the
Array.prototype changes its elements backing store to
DICTIONARY_ELEMENTS kind, which is not properly checked in all
placeswhere we test for elements in the prototype chain, i.e. in
JSObject::PrototypeHasNoElements. This causes several Array
builtins to take the slow path, i.e. Array.prototype.splice.

Fix this for now by consistently checking for either empty_fixed_array
or empty_slow_element_dictionary in both C++ and CSA runtime.

1c9de0b2c2 [scopes] Clarify and narrow when scopes care about an eval() call
There are two reasons for Scopes to need information about eval calls
inside them:

  - Eval in a scope, or any of its inner scopes, turns off a bunch of
    scope analysis optimizations (e.g., all variables have to be treated
    as "used" and context-allocated).
  - Eval in a sloppy declaration scope means allows runtime addition
    of var declarations.

This patch aims to make the code better-reflect this reality.
It's meant as a pure cleanup, with no expected change in behavior.

053918b35e PPC/s390: [turbofan] Properly check new.target parameter in inlined Reflect.construct.
Port cb9402aa98

Original Commit Message:

    The ConstructFunctionForwardVarargs and ConstructForwardVarargs
    builtins, which are used when inlining the Reflect.construct
    builtin into TurboFan optimized code, didn't properly check the
    new.target parameter whether it's a constructor.

d72c97e20b [Turbofan] Allow recursive inlining
Currently, we do not inline recursive functions. This is in general a
good idea but could be useful in some cases. For example, in rayTrace
there is a class.create function to create new classes, which basically
calls the initialize function on the object. When there are classes which
instantiate other classes this leads to recursion. These are really small
functions (within the small function budget) and it is good to inline them.
Allowing such functions to inline improves the score on rayTrace by 12-16%
and box2d by 24-30%.

There is also an absolute limit on the maximum levels of inlining to avoid
any corner cases and to ensure inlining always terminates.

fa1a339777 [async-iteration] eliminate implicit Await when resuming with .return()
AsyncGenerators, when resumed with a "return" completion, Await the sent
value to provide consistency with syntactic return statements. This
moves the await to during AsyncGeneratorResumeNext, shrinking the number
of bytecodes.

There's a minor change to BytecodeGenerator which removes a
%_GeneratorClose() call, since it's inserted implicitly by the parser.

ef0e835997 [heap] Fix clearing of slots in concurrent sweeper.
This fixes an old bug uncovered by
https://chromium-review.googlesource.com/591651

The bug is a race between the concurrent sweeper clearing slots and
the mutator adding slots and trimming fixed array:

1) The sweeper starts sweeping a page with an existing fixed array.
2) The sweeper pre-caches the slots clearing mode by checking if the
   slot set pointer on the page is null or not. (This is the bug).
3) The mutator updates the fixed array such that new slots are added.
4) The mutator trims the fixed array such that the added slots are
   now in free space.
5) The sweeper adds the trimmed part of the fixed array to free list,
   but does not clear slots there because of the cached flag.
6) A new object is allocated from the free list entry and it has
   a bogus slot entry recorded.

3e6cf71a77 [parser] Alternative fix for chromium:740591
- Previous fix is https://chromium-review.googlesource.com/c/583531 but it
  diverges Scopes created by PreParser from Scopes created by Parser.

- This CL creates the inner block scope a bit earlier and (temporarily) pushes
  it into the scope chain for parsing the variable declarations in a for
  loop. The previous approach was to first parse the variable declarations and
  then reparent the AST nodes / Scopes created while parsing it afterwards.

- This CL partially reverts https://chromium-review.googlesource.com/c/583531;
  the new fix only touches parser-base.h (diff between patch sets 2 and 3 is the
  fix).

- The Ignition golden changes are basically undoing the changes done in that CL
  too.
