This changes the BytecodeGraphBuilder interface to make the fact that
graph construction is independent of a closure explicit. A valid graph
can be constructed by providing only the pair of statically known values
for SharedFunctionInfo and TypeFeedbackVector. This is in preparation of
inlining based on the SharedFunctionInfo.

This CL modifies the ast-numbering phase to collect function literals which
should be compiled eagerly. This is then used to eagerly compile the inner
functions before compiling the outer function. This will be used to queue
compilation jobs on the CompilerDispatcher in a later CL.

This CL moves the compilation of eager inner functions out of the
GetSharedFunctionInfo function and instead compiles them explicitly. This
simplifies GetSharedFunctionInfo and also means there is no need to pass a
LazyCompilationMode to the function, so this concept has been removed.

The WasmToInterpreterFrames are not used yet; this will follow in a
follow-up CL (see tracking bug for the overall picture).
Those frames will represent frames for WASM_TO_INTERPRETER stubs, which
call from wasm code to the wasm interpreter, implemented in C++.
They will support the Summarize method to inspect the stack frames in
the wasm interpreter.

Lower StoreDataPropertyInLiteral() when storing
computed property names in object literals.

Add a new AccessMode, kStoreInLiteral. It is similar to
AccessMode::kStore but does not look
up properties on the prototype chain.

99% of all literal definitions with computed property names
end up with generic access_info because of how we count
properties. Once we fix
https://bugs.chromium.org/p/v8/issues/detail?id=5625,
they'll get lowered as well.
