Introduce the notion of an nterp frame.

See comments in nterp_helpers.cc. An nterp frame follows the
calling conventions and exception handling of the compiler. There are
no ManagedStack transitions, and the compiler and interpreter can
just call each other directly.

For the stack walker, an nterp frame looks like a compiled frame.

This CL introduces an nterp frame, another CL will contain an
implementation for x64.
