Especially for function types, this increases readability significantly.
Also the style guide recommends for 'using' over 'typedef'.

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.

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.

There's a `Map::IsDictionaryMap()` method in addition to the
`Map::is_dictionary_map()`, which apparently do very different things:
The former checks whether the instance type of the Map is in a certain
range (FIRST_DICTIONARY_TYPE to LAST_DICTIONARY_TYPE), while the latter
checks the `is_dictionary_map` bit (which means that the backing store
for the properties of a JSObject is in slow mode). To make matters worse
there's also `CodeStubAssembler::IsDictionaryMap()`, which does the bit
check similar to `Map::is_dictionary_map()`. And to make matters even
worse the FIRST_DICTIONARY_TYPE to LAST_DICTIONARY_TYPE range also
contains instance types for classes that aren't subclass of `Dictionary`
(despite a comment stating the opposite).
So in conclusion it's best to remove the confusing
`Map::IsDictionaryMap()` method, which is anyways wrong, and just test
explicitly for `NameDictionary`, `NumberDictionary` or
`GlobalDictionary` in the appropriate places.

Up until now, we cached export wrappers per export index. With the
anyref proposal potentially many more functions will need export
wrappers, e.g. any function that is stored in a table, and any
function accessed by the new ref.func instruction.
With this CL, we change the caching scheme an do the caching per
signature. Thereby we can guarantee that any export wrapper which
potentially exists can be stored in the cache.
For cctests which use wasm-run-utils, we don't know the size of the
cache anymore ahead of time. However, we assume that no more than
5 signatures will be used in any cctest. If this assumption is not
true, we can just adjust the number.
The cache is now accessed in all code paths where we need an export
wrapper.

This method is rarely used, and has several problems:
1) It CHECKs that the value is not undefined, then creates a
{Handle<T>} which again DCHECKs that the value is of type {T}.
2) It is called on a raw {FixedArray} but returns a handle.
3) It is often used when no handle is actually needed, adding
unnecessary overhead.
4) It adds complexity and hides actual checks and handlification.
This CL removes that method, replacing some uses by explicit CHECKs (in
tests) and relying on the DCHECKs in the casts otherwise.

This test needs detailed source positions which aren't available with
lazy source positions enabled so force them to always be present.

This fixes the error message generated for compile errors during
asynchronous instantiation. It shows "WebAssembly.instantiate()" now
instead of "WebAssembly.compile()".

COMPLETE events are being deprecated and don't work well with perfetto
because we can't give out a handle into the buffer like we used to so
that the caller can update the existing event with the duration.
BEGIN/END pairs should be used instead to add two separate trace events
to the buffer which can be associated with one another by the trace
processor e.g. the trace viewer UI.

This reverts commit 3dd5661204.
Reason for revert: causes leak tests in blink layout tests to fail: https://ci.chromium.org/p/chromium/builders/ci/WebKit%20Linux%20Trusty%20Leak/34295
Steps to reproduce:
- Build blink_tests with following GN args
is_component_build = false
is_debug = false
strip_absolute_paths_from_debug_symbols = true
- Run
third_party/blink/tools/run_web_tests.py --additional-expectations third_party/blink/web_tests/LeakExpectations --time-out-ms 48000 --enable-leak-detection external/wpt/wasm/webapi/body.any.html

This CL extends Error.stack to include frames of functions declared

Two changes are necessary:
- HandleApiCall and friends need to go through an BUILTIN_EXIT frame
instead of an EXIT frame. The existing stack-trace machinery will
then pick up FunctionTemplate frames without additional changes.
- Turbofan doesn't go through HandleApiCall, but instead uses an
