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.
