This removes the CompilationInfoWithZone class from the header file
because it is more than a pure convenience class and shouldn't be used
outside of the compiler at all.

This removes the stub-based constructor from CompilationInfoWithZone
as this class is more than a pure convenience class and only by chance
doesn't have an effect in the destructor.

According to Source Map specification [1] source map url can be passed either as a magic comment at the end of script or as SourceMap http header. We already parse the former value and expose it on Script object. This change allows to unify the way we deal with source map urls received in http header by providing api for passing that url into the script being compiled.
source_map_url is intentionally not passed into CompilationCacheScript::Lookup. The cache is anyways disabled when debugger is on.

Use a fake code stub instead, basically following the null object pattern.

A CompilationInfo constructed from just an Isolate* and a Zone* is in
weird an inconsistent state (calling e.g. flags() on it will crash),
so we need to avoid them. This CL removes almost all of them, the
remaining 2 call sites in (for testing only) will be handled in a
separate CL. Things which have been changed:
* Linkage is basically a decorator for CallDescriptor now.
* ChangeLowering doesn't need Linkage at all.
* JSGenericLowering doesn't need a full CompilationInfo*, just a
single flag.
* JSContextSpecializer doesn't need the full CompilationInfo, just a
Context.
* Removed unused CompilationInfo from SimplifiedLoweringTester.
This nicely decouples things already a bit more, but there's still
work to do...

This adds an "experimental" API hook (v8::ScriptCompiler::CompileModule)
allowing compilation of modules. The code gen is incredibly basic: the
module body is represented by a Block in the AST. But this at least gets
more of the pipeline working, and opens the door to writing mjsunit tests
(once d8 is modified to support module compilation).

In DevTools we need one more flag for script origin - is debugger script. We already have "is shared origin" flag. The new flag added by analogy with the old but new has accessor in script object.
