6962221295 [atomics] Relax Atomics methods to work on ArrayBuffers
This reached consensus in the March 2020 TC39.
https://github.com/tc39/ecma262/pull/1908

This aligns JS with wasm, which allows atomics operations on non-shared
linear memory.

1546be9cf8 [runtime] Move string table off-heap
Changes the isolate's string table into an off-heap structure. This
allows the string table to be resized without allocating on the V8 heap,
and potentially triggering a GC. This allows existing strings to be
inserted into the string table without requiring allocation.

This has two important benefits:

  1) It allows the deserializer to insert strings directly into the
     string table, rather than having to defer string insertion until
     deserialization completes.

  2) It simplifies the concurrent string table lookup to allow resizing
     the table inside the write lock, therefore eliminating the race
     where two concurrent lookups could both resize the table.

The off-heap string table has the following properties:

  1) The general hashmap behaviour matches the HashTable, i.e. open
     addressing, power-of-two sized, quadratic probing. This could, of
     course, now be changed.

  2) The empty and deleted sentinels are changed to Smi 0 and 1,
     respectively, to make those comparisons a bit cheaper and not
     require roots access.

  3) When the HashTable is resized, the old elements array is kept
     alive in a linked list of previous arrays, so that concurrent
     lookups don't lose the data they're accessing. This linked list
     is cleared by the GC, as then we know that all threads are in
     a safepoint.

  4) The GC treats the hash table entries as weak roots, and only walks
     them for non-live reference clearing and for evacuation.

  5) Since there is no longer a FixedArray to serialize for the startup
     snapshot, there is now a custom serialization of the string table,
     and the string table root is considered unserializable during weak
     root iteration. As a bonus, the custom serialization is more
     efficient, as it skips non-string entries.

As a drive-by, rename LookupStringExists_NoAllocate to
TryStringToIndexOrLookupExisting, to make it clearer that it returns
a non-string for the case when the string is an array index. As another
drive-by, extract StringSet into a separate header.

This is a stop-gap solution (while we wait for a proper spec)
that lets managed WasmGC objects perform round-trips through

1a9c73c3c9 cppgc: github: Add initial version of cmake generator
The parser is capable of processing full GN grammar. The generator uses
the visitor and the builder patterns. The visitor handles call expressions
(e.g. target declarations), GN expressions (e.g. is_clang && !is_win),
conditional and assignment statements. Builder is used to generate a
particular output. For example, this CL brings in CMakeBuilder for cmake
generation, but same infrastructure can be reused for generation of
amalgamated sources.

Things that are not yet automatically generated:
1) Automatic generation of config variables (from declare_args).
2) Dependency scanning. Since we only have limited number of targets,
   this is not a big issue at the moment.

Followup CLs will include:
- test targets;
- sample targets.

a269ce201d Revert "Reland "[flags] warn about contradictory flags""
This reverts commit d8f8a7e210.

Reason for revert: Breaks code_serializer variant - https://cr-buildbucket.appspot.com/build/8874070652992164976

Original change's description:
> Reland "[flags] warn about contradictory flags"
> 
> This is a reland of b8f9166664
> Difference to previous CL: Additional functionality to specify
> incompatible flags based on GN variables and extra-flags, used
> to fix the issues that came up on the waterfall.
> 
> This also changes the rules regarding repeated flags: While
> explicitly repeated flags are allowed for boolean values as long
> as they are identical, repeated flags or explicit flags in the
> presence of an active implication are disallowed for non-boolean
> flags. The latter simplifies specifying conflict rules in
> variants.py. Otherwise a rule like
> 
> INCOMPATIBLE_FLAGS_PER_EXTRA_FLAG = {
>   "--gc-interval=*": ["--gc-interval=*"],
> }
> 
> wouldn't work because specifying the same GC interval twice
> wouldn't actually count as a conflict. This was an issue with
> test/mjsunit/wasm/gc-buffer.js, which specifies
> --gc-interval=500 exactly like the extra flag by the stress bot.
> 
> Also, this now expands contradictory flags checking to d8 flags
> for consistency.
