Add the ability to return (multiple) return values on the stack:
- Extend stack frames with a new buffer region for return slots.
This region is located at the end of a caller's frame such that
its slots can be indexed as caller frame slots in a callee
(located beyond its parameters) and assigned return values.
- Adjust stack frame constructon and deconstruction accordingly.
- Extend linkage computation to support register plus stack returns.
- Reserve return slots in caller frame when respective calls occur.
- Introduce and generate architecture instructions ('peek') for
reading back results from return slots in the caller.
- Aggressive tests.
- Some minor clean-up.
So far, only ia32 and x64 are implemented.

In snapshots with several contexts, some contexts may not reference
function or object templates, and therefore would not require external
references for deserialization. However, function and object templates
are deserialized with the isolate as part of the partial snapshot cache,
so we would need these external references even if we only use contexts
that don't need them.
With this patch, we use a fallback in case no external references are
provided. This way, we only run into issues when we actually call native
callbacks.

They have the same lifetime. It's a match!
Both structures are native context dependent and dealt with (creation,
clearing, gathering feedback) at the same time. By treating the spaces used
for literal boilerplates as feedback vector slots, we no longer have to keep
track of the materialized literal count elsewhere.
A follow-on CL removes even more parser infrastructure related to this count.
