6a72f3731b [compiler] Make Compiler::EnsureBytecode respect filter.
This ensures that {Compiler::EnsureBytecode} fails gracefully in case
the --ignition-filter flag prevents generation of bytecode for a certain

642d6d314c Rework scanner-character-streams.
- Smaller, more consistent streams API (Advance, Back, pos, Seek)
- Remove implementations from the header, in favor of creation functions.

Observe:
- Performance:
  - All Utf16CharacterStream methods have an inlinable V8_LIKELY w/ a
    body of only a few instructions. I expect most calls to end up there.
  - There used to be performance problems w/ bookmarking, particularly
    with copying too much data on SetBookmark w/ UTF-8 streaming streams.
    All those copies are gone.
  - The old streaming streams implementation used to copy data even for
    2-byte input. It no longer does.
  - The only remaining 'slow' method is the Seek(.) slow case for utf-8
    streaming streams. I don't expect this to be called a lot; and even if,
    I expect it to be offset by the gains in the (vastly more frequent)
    calls to the other methods or the 'fast path'.
  - If it still bothers us, there are several ways to speed it up.
- API & code cleanliness:
  - I want to remove the 'old' API in a follow-up CL, which should mostly
    delete code, or replace it 1:1.
  - In a 2nd follow-up I want to delete much of the UTF-8 handling in Blink
    for streaming streams.
  - The "bookmark" is now always implemented (and mostly very fast), so we
    should be able to use it for more things.
- Testing & correctness:
  - The unit tests now cover all stream implementations,
    and are pretty good and triggering all the edge cases.
  - Vastly more DCHECKs of the invariants.

e1997bb7d7 [Tracing] Remove unnecessary memory allocation in runtime call stats.
Previously we didn't implement TRACE_STR_COPY when we write trace events to
file, which causes us to allocate a growing independent memory chunk for dumped
runtime call stats table. Since we now have a fully functional TRACE_STR_COPY,
this memory allocation can be avoided, this patch removes it.

834aec3391 Class fields, part 2 (desugaring)
This is one part of a WIP implementation of the stage-2 proposal to add
fields to classes: https://github.com/tc39/proposal-class-public-fields

See design doc:
https://docs.google.com/document/d/1WRtNm3ZLNJT1WVr8aq4RJuByYgfuAFAhj20LwTW6JVE/

This adds the desugaring logic to the parser. It isn't usable without
the (forthcoming) backend changes.

fe6b76d491 Class fields, part 1 (parsing and infrastructure)
This is one part of a WIP implementation of the stage-2 proposal to add
fields to classes: https://github.com/tc39/proposal-class-public-fields

See design doc:
https://docs.google.com/document/d/1WRtNm3ZLNJT1WVr8aq4RJuByYgfuAFAhj20LwTW6JVE/

This adds support for parsing fields in classes, including
infrastructure. In particular, it adds:
* Two booleans on function literal AST nodes
* Two compiler hints on SharedFunctionInfos representing said bools
* A new type of ClassLiteralProperty, FIELD
* Parser support for the syntax
* Syntax tests
* A flag to enable it.

Currently the fields are parsed and then droppped. Subsequent
patches will add semantics, mostly by desugaring in the parser and
the remainder in the non-crankshaft backends.

9df94139d8 Introduce PREPARE_FOR_EXECUTION_WITH_CONTEXT_IN_RUNTIME_CALL_STATS_SCOPE
Previously, macro like PREPARE_FOR_EXECUTION_WITH_CALLBACK will end up calling
LOG_API, where we create a runtime call timer scope when we enable tracing with
runtime call stats, however since the flag will be enabled after calling
TRACE_EVENT_CALL_STATS_SCOPED, this will end up with incorrect timestamp. Thus,
we introduce a new macro
PREPARE_FOR_EXECUTION_WITH_CONTEXT_IN_RUNTIME_CALL_STATS_SCOPE, which will call
TRACE_EVENT_CALL_STATS_SCOPED inside it.

94492437d9 Fully deserialize the scope chain after parsing, not before
To avoid a dependency on the heap during parsing, we only create a scope chain
without linking to the associated ScopeInfo objects before parsing. This is
enough to avoid special cases during parsing of arrow functions / eval.

Looking at the outer scope's variables during parsing was only needed for hosting
sloppy block functions inside eval. To be able to do this now, we hoist for the
outer-most eval scope after parsing, in DeclarationScope::Analyze.

DeclarationScope::Analyze is also where we replace the outer scope chain with the
fully deserialized version, so variables can be resolved.

Also, this unifies background and foreground thread parsing, as we don't have to
worry about ScopeInfos getting accessed before we're back on the main thread.

8439401d2d [runtime] Intercept function declarations.
We used to intercept function definitions, but not declarations.
GenericNamedPropertySetterCallback now also intercepts function declarations.

For definitions, we call DeclareGlobal and then InitializeVarGlobal. For
declarations, we never call InitializeVarGlobal, thus we must check for
interceptors in DeclareGlobal.

If the semantics of a redeclaration are wrong, e.g., redeclaring a read-only
property, an exception is thrown independent of whether an interceptor is
installed. Usually, i.e., not during a declaration, we only throw if
the call is not successfully intercepted.

3f0c881980 PPC/s390: [turbofan] Collect invocation counts and compute relative call frequencies.
Port c7d7ca361d

Original commit message:

    Add a notion of "invocation count" to the baseline compilers, which
    increment a special slot in the TypeFeedbackVector for each invocation
    of a given function (the optimized code doesn't currently collect this
    information).

    Use this invocation count to relativize the call counts on the call
    sites within the function, so that the inlining heuristic has a view
    of relative importance of a call site rather than some absolute numbers
    with unclear meaning for the current function. Also apply the call site
    frequency as a factor to all frequencies in the inlinee by passing this
    to the graph builders so that the importance of a call site in an
    inlinee is relative to the topmost optimized function.

    Note that all functions that neither have literals nor need type
    feedback slots will share a single invocation count cell in the
    canonical empty type feedback vector, so their invocation count is
    meaningless, but that doesn't matter since we only use the invocation
    count to relativize call counts within the function, which we only have
    if we have at least one type feedback vector (the CallIC slot).

    See the design document for additional details on this change:

b37daacd6b [Interpreter] Localize the CanonicalHandleScope to parsing and renumbering.
Ignition requires that objects which will be inserted into the
constant pool are canonicalized (to enable off-thread bytecode
generation). We created a CanonicalizeHandleScope across parse/compile
however this impacts performance (~5-8% on CodeLoad).

Now we localize the CanonicalHandleScope to only the parse /
internalization and renumbering phases where objects are created which
could end up in the constant array pool. This seems to address
the performance regression.
