c5d25ec2f8 [torque-ls] Allow compilation of plain std::string inputs
This CL refactors the torque-compiler module slightly to allow
compilation of string inputs in addition to file path inputs. The
added functionality is then used to implement the first
'goto type defintion' unit test.

e00f2de6b5 [torque-ls] Properly decode file URIs sent by the client
This CL changes the language server to store file paths as URIs and
decodes them on-demand during compilation. For now, this will
eliminate the need for an URI encoding function.

f35ad6ecd4 [torque-ls] Port tests from cctest to unittest
Moving to gtest allows negative test cases as the current parser
implementation exits the process on a parser error. The CL adds two
small negative tests. The idea is less to get full coverage, but to
have a place for regression tests.

Drive-by-change: Lexer errors need a valid source position scope and
Json parser needs a valid SourceId, otherwise we read OOB when the
error message is generated.

3f8b031647 [zone] Remove segment pooling from accounting allocator
This pooling introduces severe lock contention for Liftoff compilation,
since each compilation uses its own Zone which does at least one
segment allocation.
It's also unclear whether pooling improves performance, since {malloc}
should implement a similar pooling mechanism, but better optimized for
multithreaded uses.

Feel free to revert if this introduces significant regressions.

803ad32414 Reland "Optimize in operator"
The original was reverted for breaking webkit layout tests:
https://ci.chromium.org/p/v8/builders/luci.v8.ci/V8-Blink%20Linux%2064/30270

It also caused the following clusterfuzz failures:

chromium:935832
This was a correctness bug due to not properly handling the case of arrays with prototypes other
than Array.prototype. Accesses that were TheHole were not being handled property, both in bounds
holes in holey arrays and out of bounds on either holey or packed arrays. Handling was incorrect
both in access-assembler and in Turbofan.

chromium:935932
This bug was that there was no handling for Has checks on the global object. Turbofan was emitting
code for a store (the 'else' condition on 'access_mode == AccessMode::kLoad'). It hit a DCHECK in
debug builds but in release could show up in different places. This is the bug that caused the
webkit layout test failure that led to the revert.

Both bugs are fixed by in CL, and tests are added for those cases.

c7ebc5814f Reland "[ignition] Skip binding dead labels"
This is a reland of 35269f77f8

Switches on an expression that unconditionally throws would have all their
case statements dead, causing a DCHECK error in the SwitchBuilder. This
fixes up the DCHECK to allow dead labels.

Original change's description:
> [ignition] Skip binding dead labels

> writer. Conveniently, this means that we can be a bit smarter about basic
> blocks around these statements.
>
> As a drive-by, remove the unused Bind(target,label) function.

There is a dead node arriving in representation selection, which might indicate that the problem is not in this CL, but that this CL stirs up the node soup in such a way that dead code elimination gets confused.

b152bb75f8 [heap] Relax accessing markbits in ranges.
When calling the `bitmap(chunk)` method of the various *MarkingState accessors
we would receive a raw `Bitmap` pointer which does not tell you if accesses to
markbits should be made atomically or not. As a result, we would default to
doing atomic operation when in fact it may not be necessary.

Here we're introducing a templated `ConcurrentBitmap` class that wraps
operations done on the markbits and allows them to be made non-atomic.

Additionaly, some of the `Bitmap` methods were only used to verify the heap and
in the tests so they do not need atomic implementations. Using them in a
concurrent context should now fail to link to make sure they're not mis-used in
the future.

ff8f4144db [heap] Simplify idle notification handler
This merges the "do-nothing" case with the "done" case as the former
is no longer useful. This also fixes a bug where the idle time handler

4d9381baa6 test: Replace _TEST_CASE_ with _TEST_SUITE_.
Googletest is (at last) converging with industry-standard terminology
[1]. We previously called test suites "test cases", which was rather
confusing for folks coming from any other testing framework.

Chrome now has a googletest version that supports _TEST_SUITE_ macros
instead of _TEST_CASE_, so this CL cleans up some of the outdated usage.

8c30a2ccc0 [testrunner] migrate testsuites to lazy loading
V8 test suites return tests by loading them into memory up-front. Up-front
loading has memory and loading-time overhead for the testrunner.

This CL converts the test-suites to load tests during the test run in parallel.

After CL, most test suites start running immediately and all test suites start
running after 3 seconds on a modern SSD.

This CL eliminates the 200 MiB memory spikes that causes memory problems in mac
minis.

Overhead of running test262 before CL:
Line #    Mem usage     Increment   Line Contents
=================================================
   264  225.760 MiB 195.8.000 MiB         tests = self._load_testsuite_generators(args, options)
-------------------------------------------------
Overhead of running test262 after CL:
Line #    Mem usage    Increment   Line Contents
================================================
   264   28.840 MiB    0.000 MiB         tests = self._load_testsuite_generators(args, options)
