Reduce the enqueuing cost of compiler-dispatcher jobs by getting rid of
the sets and hashmaps, and instead:
1. Turning the pending job set into a queue, and
2. Making the SharedFunctionInfo's UncompiledData hold a pointer to
the LazyCompilerDispatcher::Job, instead of maintaining an
IdentityMap from one to the other.
To avoid bloating all UncompiledData, this adds two new UncompiledData
subclasses, making it four subclasses total, for with/without Preparse
data and with/without a Job pointer. "should_parallel_compile"
FunctionLiterals get allocated an UncompiledData with a job pointer by
default, otherwise enqueueing a SFI without a job pointer triggers a
reallocation of the UncompiledData to add a job pointer.
Since there is no longer a set of all Jobs (aside from one for
debug-only), we need to be careful to manually clear the Job pointer
from the UncompiledData whenever we finish a Job (whether successfully
or by aborting) and we have to make sure that we implicitly can reach
all Jobs via the pending/finalizable lists, or the set of currently
running jobs.

Note that this CL does not make it safe yet to access character data

--wasm-speculative-inlining makes no sense if --liftoff-only or

Add suppose for compiling non-eager, non-top-level inner functions in
parallel, using the compiler dispatcher. This behaviour can be enabled
with --parallel-compile-tasks-for-lazy.
There are a couple of consequences:
* To support this we need support for off-thread ScopeInfo
deserialization, so this adds that too.
* The previous --parallel-compile-tasks flag is renamed to the more
descriptive --parallel-compile-tasks-for-eager-toplevel.
* Both parallel-compile-tasks flags are moved onto
UnoptimizedCompileFlags so that they can be enabled/disabled on a
per-compile basis (e.g. enabled for streaming, disabled for
re-parsing).
* asm.js compilations can now happen without an active Context (in
the compiler dispatcher's idle finalization) so we can't get a
ContextId for metric reporting; we'd need to somehow fix this if we
wanted asm.js UKM but for now it's probably fine.
* Took the opportunity to clean up some of the "can preparse" logic in
the parser.

Design doc: bit.ly/3jEVgzz
We separate the internal representation of function references in Wasm
from their JSFunction-based (external) representation. This improves
performance of call_ref by requiring less indirections to load the
context and call target from a function reference. In the boundary
between wasm and JS/the C API, we add transformations between the two
representations.
Detailed changes:
- Introduce WasmInternalFunction, containing fields required by
call_ref, as well as a reference to the corresponding
WasmExternalFunction. Add a reference to the WasmInternalFunction in
WasmFunctionData. The {WasmInternalFunction::FromExternal} helper
extracts the internal out of an external function.
- Change {WasmInstanceObject::external_functions()} to internal
functions.
- Change wasm function tables to contain internal functions.
- Change the following code to use internal functions:
- call_ref in liftoff and Turbofan
- function type checks in liftoff and Turbofan
- CallRefIC and GenericJSToWasmWrapper builtins
- {InitExprInterface::RefFunc}
- module-compiler.cc in {ProcessTypeFeedback}
- In module-instantiate.cc, in function-rtt creation.
- Add transformations between internal and external functions in:
- WasmWrapperGraphBuilder::{ToJS, BuildUnpackObjectWrapper, FromJS,
BuildJSToJSWrapper}.
- debug-wasm-objects.cc in {FunctionProxy::Get},
{WasmValueObject::New} and {AddWasmTableObjectInternalProperties}.
- runtime-wasm.cc in ReplaceWrapper
- the C and JS APIs
- module-instantiate.cc, in import and export processing, as well as
{InitializeIndirectFunctionTables}
- WasmTableObject::{IsValidElement, SetFunctionTableEntry}
- {WasmGlobalObject::SetFuncRef}
- Simplify body descriptors of WasmExternalFunction variants.
- Adjust tests.

Prior to this CL we regularly generated high counts of code
dependencies, and installation was not the most efficient.
This CL 1) implements early dependency deduplication and
2) simplifies the way dependencies are persisted on the heap
through DependentCode.
Re 1): we dedupe twice, once based on the CompilationDependency
contents, and again once we know the final target object.
Re 2): Instead of a linked list of weak fixed arrays per
dependency group, store deps in a flat array together with a
bitset of their dependency groups.

Disable --concurrent-inlining when v8_dict_property_const_tracking is
enabled, since the latter doesn't support the former. Add statusfile
variables to mark this as an incompatible flag, and otherwise disable it
via flags.

The gdb DCHECK frame skipping automatically skips over all the abort
etc. frames to get you to that DCHECK callsite you're actually looking
for.
However, this is annoying if you tried to call a function with a
breakpoint from the gdb prompt; the frame skipping wold skip over your
breakpoint back up to the failing DCHECK.
Now, we abort the frame walk on dummy frames inserted by gdb execution.
