Instead, it is supposed to just return an empty context if it failed.
Also don't invoke interceptors (we don't for the parts that deserialize
from the snapshot anyways).

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.

The WasmRunner now always holds a TestingModule, and allows to add
several functions to it. The prepares a change to always run wasm code
with a full module behind it, removing the special handling for "no wasm
instance" at runtime (http://crrev.com/2551053002).
This CL here also templatizes the WasmRunner such that the Call method must
be called with the same signature specified for the WasmRunner. This
already catched several mismatches there.

In captured stack traces, all lines and columns must be 1-based.
Even though this makes things a bit ugly, we have to comply also for
wasm locations, where line and column encode function index and byte
offset (both are originally 0-based).
If we don't comply, the frontend might complain, as e.g. DevTools does.

We report the byte offset as column number, but devtools assumes them
to be 1-based and subtracts one unconditionally before further
processing it. It's a bit unfortunate, but because of that we have to
just add 1 to the reported column number on the public StackTrace API.

Empty function names are allowed and are output as such, unnamed
functions or functions with no valid UTF-8 name are output as
"<WASM UNNAMED>", while the CallSite object returns null as the
function name.
