c7d57dd309 [regexp] Reduce public API surface
This further reduces the number of things declared in the public
regexp API file, currently still named jsregexp.h.

* Move JSRegExp::Flags convenience functions to regexp-compiler.h.
* Set RegExpImpl methods private if possible (these will later be
  moved to a new hidden impl class).
* Merge RegExpEngine::CompilationResult into RegExpCompileData.
* Move remaining RegExpEngine methods to RegExpImpl and delete
  RegExpEngine.
* Extract RegExpGlobalCache.
* Document a few data structures.

Upcoming CLs will rename RegExpImpl to RegExp and jsregexp.h to
regexp.h. This should then be the only header included from other
directories.

8e0ef9b9a0 Add fast path for proxy with preventExtensions trap
ObjectPreventExtensions and ReflectPreventExtensions are now Torque builtins (previously CPP) and the Proxy path is implemented completely in Torque while everything else calls into runtime (and is thus a bit slower than previously).

Perf improvement in micro-benchmark JSTests/Proxies
Before:
PreventExtensionsWithoutTrap-Proxies(Score): 1978
PreventExtensionsWithTrap-Proxies(Score): 739

After:

1eee4e1ee5 Port BigInt addition to Torque
Implements the addition of BigInts as a Torque builtin, which performs necessary

MutableBigInt::AbsoluteSub and MutableBigInt::AbsoluteCompare is now used by both
the runtime and the Torque generated builtin for best performance.

f993a9c9cc [roheap] Inform lsan of leaked objects during read-only space set up
Without this, asan (rightfully) complains about read-only space leaking.

Because pages are manually allocated using mmap, a few objects within
them need to be explicitly ignored in addition to the read-only heap
itself.

This change re-adds lsan.h, with tweaks to make the type checking a bit
more lenient.

19d8bfa5a8 [torque] no longer generate assemblers per namespace
Instead of generating one CodeStubAssembler-like class per namespace,
Torque-generated macros are now free-standing functions not included
from CSA code, and explicitly exported macros become part of the new
TorqueGeneratedExportedMacrosAssembler, which CodeStubAssembler
inherits from, thus making them available to all CSA code.

Structs are now defined in a new header csa-types-tq.h as free-standing
types with the prefix "TorqueStruct".

This is a preparation for generating per Torque-file instead of per
namespace.

d365f62ec1 [tracing] Add a way to test perfetto traces.
Add a new abstract class TraceEventListener which is just an interface
for consuming trace events. This separates the V8-specific stuff that
an actual perfetto consumer needs to do e.g. handling the has_more flag
and signalling back to the controller with a semaphore.

This is a change from the previous plan of making the PerfettoConsumer
class sub-classable to implement custom consumption of trace events.
This will be difficult when the consumer is created outside of the
PerfettoTracingController as we can't hook up the
consumer_finished_semaphore_ that belongs to the controller.

Now the PerfettoTracingController is responsible for the Consumer life-
cycle and hides it entirely from callers. We add the
AddTraceEventListener() method to allow callers to register a listener
either for testing or a JSON listener for real tracing.

This lets us write tests that can store all the trace events in memory
without first converting them to JSON, letting us write test more
easily. There's an example test add to test-tracing - more tests using
this style will follow.

9a2e4693a0 [tracing] Add a perfetto consumer base class
Split the JSONConsumer into a base case and subclass so that we can
implement different consumers without needing to repeat the code that
deals with the finished semaphore and endpoint setters/getters.

This makes it possible to add a test consumer that just holds the trace
events in memory in a later CL.

This CL re-uses the existing perfetto-consumer.h file to some extent,
but it was accidentally leftover from a previous CL where we stopped
using it and switched to the JSON consumer instead.
