Change compared to last reland:
- Do not check for d8 flag contradictions in the presence of --fuzzing
- Allow identical re-declaration of --cache=*

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.

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.

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.

With work on NCI proceeding, it makes sense to test multiple
pipeline configurations.
The nci variant (passes --turbo-nci) now spawns dedicated NCI
compilation jobs and inserts generated code into the code cache.
The nci_as_highest_tier variant (passes --turbo-nci-as-highest-tier)
simply replaces TF with NCI code (no extra jobs, no extra caching).
This mode stresses NCI generated code more than the nci variant, in
which NCI code only runs on cache hits.

Previously we ran baseline (e.g. ignition) and one random secondary
comparison configuration (e.g. turbofan) from the list of experiments.
But Clusterfuzz imposes limitations on the total amount of fuzz tests.
Therefore this change enables more throughput by always running the
default configuration (ignition_turbofan like V8 is shipped)
additionally to the baseline and the secondary configuration.
This, hence, doubles the number of comparisons we run, with less than
50% additional runtime, since the slow baseline configuration is only
run once.
The experiments table is updated accordingly. Explicit entries running
ignition_turbofan are removed (as it always runs now), instead some
of the other configurations are increased in their relative
percentage. We also get a few new configurations that didn't run
before (e.g. forcing the slow path on x86).

This shares the code of running the comparisons on the fuzz test

the fuzz test, the smoke test has slight changes in favor of code
readability:
1. Smoke tests can now bail out on output suppressions (There are
none now. And if we'd ever add any we'd need to write them in a way,
such that they ignore the output of the smoke tests, which don't
have much output anyways).
2. Crashes in smoke tests are now a hard failure. This is a desired
feature anyways. It's unlikely that the smoke test crashes as then
nothing would work.

This simplifies the lengthy main method by extracting some code and
by replacing the scattered returns with exceptions.
We introduce two exceptions for early bail-out. This enables helper
methods on multiple layers. The early bail-out on time-out is
moved to the point where it is detected.
Previously on timeout and crash we also printed out the step number.
Clusterfuzz doesn't parse this, it was only for statistical purposes,
and the latest version of the experimental workbench only parses
crashes and timeouts, not the step in which they happened. Hence,
this CL removes those step numbers.
Except the change described in the last paragraph, this CL doesn't
intend to change behavior.
