This simplifies the mark getter enough to generate a branch-free check
on many architectures (e.g. using cmov on x64 or csel on ARM).

As a drive-by, we can now make the mark access const.

makes V8's Intl implementation follow the specification's logic to avoid

This CL implements GetPossibleBreakpoints for wasm, by iterating over
all functions in the requested range and returning the location of all
instructions within that range.

The connection to the inspector will be added later, when setting
breakpoint also works for wasm: http://crrev.com/2536763002

When executing wasm code for testing, we did not create a
WasmInstanceObject and link it to the generated code. This required
some special handling at runtime (mainly for stack trace generation).
This CL always provides the WasmInstanceObject, such that e.g. function
names can be resolved the usual way.
The module bytes referenced by the WasmCompiledModule linked with the
WasmInstanceObject do not hold a valid wasm module yet. Instead, we
just add the bytes we need, and make the objects in WasmModule point to
those bytes (currently only used for function names). Those bytes will
not be parsed at runtime anyway.
