Rather than storing the isolate in compiler dispatcher jobs, which gets
weird for jobs that are entirely off-thread, instead pass the isolate
in when stepping on the main thread.
This makes it clearer which steps must be executed on the main thread,
as they require the caller to explicitly give them access to the
isolate.

The approach to creating compiler dispatcher jobs for inner functions after
they had been parsed didn't provide the startup benifits we hoped for due
to the need to hold onto the whole zone memory AST while waiting for the
jobs to complete.
This CL removes the ability to create these compilation jobs (which was never
enabled by default anyway). Going forward we will potentially use the
parser task approach to parse+compile inner functions in their own job.

whether that function calls eval. All that matters is that the ancestor

They're supposed to be stable across several parse passes, so we'll also
store them in the associated SharedFunctionInfos
To achieve this, the PreParser and Parser need to generated the same number of
FunctionLiterals. To achieve this, we teach the PreParser about desuggaring of
class literals.
For regular functions, the function IDs are assigned in the order they occur in
the source. For arrow functions, however, we only know that it's an arrow function
after parsing the parameter list, and so the ID assigned to the arrow function is
larger than the IDs assigned to functions defined in the parameter list. This
implies that we have to reset the function ID counter to before the parameter list
when re-parsing an arrow function. To be able to do this, we store the number of
function literals found in the parameter list of arrow functions as well.

This means we can no longer take the closure's context to parse, but
need to rely on the outer scope info.
Since it's not possible to get that, however, for lazy functions, we
introduce a new field to SharedFunctionInfo that stores the outer scope
info whenever available.

To avoid a dependency on the heap during parsing, we only create a scope chain
without linking to the associated ScopeInfo objects before parsing. This is
enough to avoid special cases during parsing of arrow functions / eval.
Looking at the outer scope's variables during parsing was only needed for hosting
sloppy block functions inside eval. To be able to do this now, we hoist for the
outer-most eval scope after parsing, in DeclarationScope::Analyze.
DeclarationScope::Analyze is also where we replace the outer scope chain with the
fully deserialized version, so variables can be resolved.
Also, this unifies background and foreground thread parsing, as we don't have to
worry about ScopeInfos getting accessed before we're back on the main thread.

Rebuilding (after touching certain files) is crazy slow because
includes are out of control.

Adds compile operations to the CompilerDispatcherJob interface. As such,
introduces Compiler::PrepareUnoptimizedCompilationJob and updates the
unoptimized compilation path to use CompilationJobs. Also unifies
FinalizeCompilationJob to deal with both optimized and unoptimized
compilation jobs.
A dummy FullCodegenCompilationJob is also introduced, where all the work
is done in the ExecuteJob phase, which cannot be run on a
background thread.

When preparing compilation, we can't delay error reporting either.
Also put handles during internalization into a deferred handle scope.

This makes us able to get rid of dependencies to parser.h from places
which only need the ParseInfo, and also gets rid of the curious Parser
<-> Compiler circular dependency.
Also IWYUd where necessary.
