[Interpreter] Support top-level code.

[Interpreter] Support top-level code.

Adds support for compiling top level code to bytecode to be run in the
interpreter.

Also moves PassesFilter to String:: so that it can be used to filter top
level script names as well as functions (used in
https://codereview.chromium.org/1379093002/)

Ping?

LGTM to unblock things. I am fine with addressing my issues later and just
having TODOs for now.

https://codereview.chromium.org/1372293005/diff/20001/src/compiler.h
File src/compiler.h (right):

https://codereview.chromium.org/1372293005/diff/20001/src/compiler.h#newcode470
src/compiler.h:470: Handle<BytecodeArray> bytecode_array_;
As discussed offline: I am not a huge fan of this being carried along in the
CompilationInfo, can we leave a TODO that this is a temporary workaround? Feel
free to name me in the TODO.

https://codereview.chromium.org/1372293005/diff/20001/src/objects.h

src/objects.h:8689: bool PassesFilter(const char* raw_filter);
As discussed offline: Can we add a TODO here that this is a temporary workaround
until compiler.cc can use JSFunction::PassesFilter for top-level code. Feel free
to name me in the TODO.

[rmcilroy, 2015-10-07 10:05:37]

Thanks Michi. TODOs added. Happy to help address the TODOs once you've got
compiler.cc the way you want it.
