6053f4a331 [parser]: Skipping inner funcs / initial implemetation of storing scope analysis data from preparsed scopes.
The data produced at the moment only contains information about scope type +
positions, and only the most trivial tests pass.

Upcoming CLs will extend the data to contain information about variables (once
PreParser can produce it) and add more test cases.

98dbcfde26 Conditionally convert V8 build overrides to declare_args.
We're converting the build_overrides system to the new default_args list of
overrides that can be listed in the toplevel .gn file. This will allow args to
be set on a per-repo basis.

This change conditionally adds the variables currently defined in
build_overrides/v8.gni to build args. This allows V8's build to be used in both
the new and old systems. Once all Chrome and pdfium have been updated, v8's
build overrides and the conditional checks around the new args can be removed.

2c1d1e6088 [build] Introduce an embedder version string
Sometimes, the embedder might want to merge a fix to an abandoned branch
or to a supported branch but the fix is not relevant to Chromium.
This adds a new version string that the embedder can set on compile time
and that will be appended to the official V8 version.
The separator must be provided in the string. For instance, to have a
full version string like "5.5.372.37.custom.1", the embedder must set
V8_EMBEDDER_STRING to ".custom.1".

226e454069 includes: move Label out of assembler.h.
E.g., ast/ast.h uses Label but shouldn't need to include assembler.h for that. With
this change, we can hope for proper layering in the future (not quite there
yet).

Also includes minor random include lowering and relevant IWYU fixes.

02149d89a5 Include harmony-string-padding.js in the context snapshot
The attached chromium bug suggests that turning this on via a flag
regressed a perf test. Having previously run into slowdowns due
to experimental JS natives, my suspicion is that this regression
can be fixed by including the new builtins in the snapshot.
My intention is to land this patch to see if the regression
goes away on the bots.

Given the nature of this feature, it seems low-risk to remove
the runtime flag. If need be, it would be trivial to craft
a patch to remove these two methods from String.prototype
if we run into web compat issues during the release (note
that no release branch has yet picked up this feature).

af38272dd9 Optimize case conversion with icu_case_mapping
Use FastAsciiConvert (as used by Unibrow) for i18n-aware
case conversion with --icu_case_mapping.

Move FastAsciiConvert to src/string-case.cc so that it can be used
by both runtime-{string,i18n}.

Add more tests.

0a3c8fc3ef [Tracing] Implement IC statistics in tracing.
This patch introduces:

1. ICStats class to store ic statistics items produced by V8,
2. A disabled by default tracing category v8.ic_stats,
3. An trace event V8.ICStats that contains ic statistics items in args,

We store ic statistics items in an array until the array is full to reduce
the number of trace events.

d26cdb7d6f v8::Private::ForApi should be context-independent.
This is done by reimplementing Symbol.for directly on top of
NameDictionary. A nice side effect is the removal of src/js/symbol.js

f5fb2da64c [inspector] Split off interface-types.h
This CL adds a new header src/debug/interface-types.h, moves the
definition of Location from the debug-interface.h to this new header,
and adds a new definition for the WasmDisassembly types.
This allows to use the types in other implementation files or headers
without having to include the entire debug-interface.h, reducing build
dependencies and compile time (especially for incremental builds).

The WasmDisassembly type replaces the old
std::pair<std::string, std::vector<std::tuple<...>>>, which was a bit
hard to unravel.

b9d930735a [ignition] Rewrite reverse iterator as random iterator
This allows us to optimise the bytecode liveness analysis to jump
directly to previously seen indices. The analysis is optimised to store
a stack of loop ends (JumpLoop bytecode indices), and iterate through
these indices directly rather than looping through the bytecode array to
find them.

bf35d15e52 [wasm] OOB traps: build protected instruction list during codegen
During codegen, we build a list mapping protected instructions to their
associated landing pads. This will ultimately by used by the signal handler to
recover from out of bounds faults and throw a JS exception.

This is mostly pulled from my larger in-progress CL at
https://codereview.chromium.org/2371833007/.

2bf71f888f [ignition/turbo] Perform liveness analysis on the bytecodes
Replaces the graph-based liveness analyzer in the bytecode graph builder
with an initial bytecode-based liveness analysis pass, which is added to
the existing loop extent analysis.

Now the StateValues in the graph have their inputs initialised to
optimized_out, rather than being modified after the graph is built.

cfebe6034c Assign unique IDs to FunctionLiterals
They're supposed to be stable across several parse passes, so we'll also
store them in the associated SharedFunctionInfos

To achieve this, the PreParser and Parser need to generated the same number of
FunctionLiterals. To achieve this, we teach the PreParser about desuggaring of
class literals.

For regular functions, the function IDs are assigned in the order they occur in
the source. For arrow functions, however, we only know that it's an arrow function
after parsing the parameter list, and so the ID assigned to the arrow function is
larger than the IDs assigned to functions defined in the parameter list. This
implies that we have to reset the function ID counter to before the parameter list
when re-parsing an arrow function. To be able to do this, we store the number of
function literals found in the parameter list of arrow functions as well.
