Linkage-related methods were declared in wasm-compiler.h and
implemented in wasm-linkage.cc. This required all users of e.g. wasm
call descriptors to include the whole wasm compiler header. Also, some
wasm linkage information is independent of turbofan and also used
outside of the compiler directory.
This CL splits off wasm-linkage.h (with minimal includes) and puts it
in src/wasm. This allows to use that information without including
compiler headers (will clean up several uses in follow-up CLs).

This refactoring is a big step towards separating Turbofan-related code
from backend independent code. This will allow us to include way less
headers from "src/compiler" at various places.
The {WasmCompilationUnit} contained information for Turbofan
compilation, and for Liftoff compilation. This CL tears this apart, such
that {WasmCompilationUnit} holds backend-independent information, plus
a pointer to either {LiftoffCompilationUnit} or
{TurbofanWasmCompilationUnit}. These pointers are opaque, so that
{function-compiler.h}, defining {WasmCompilationUnit}, does not need to
include any Turbofan specific or Liftoff specific headers.

This change makes lifetime management of WasmCode much simpler.
By using the WasmInstanceObject as the context for WASM code execution,
including the pointer to the memory base and indirect function tables,
this keeps the instance alive when WASM code is on the stack, since
the instance object is passed as a parameter and spilled onto the stack.
This is in preparation of sharing the code between instances and

As part of J2V8 development (https://github.com/eclipsesource/J2V8),
we realized that we had a subtle bug in how Isolate scope was created
and it's lifetime managed, see:
https://github.com/eclipsesource/J2V8/issues/313.
Mentioned above bug was fixed, however, what we also noticed is that
V8 API has been constantly and slowly moving to such an API, in which
one has to pass Isolate explicitly to methods and/or constructors. We
found two more places that might have been overlooked. This contribution
adds passing of Isolate pointer explicitly to constructors of
String::Utf8Value and String::Value classes.

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.

This changes different locations to extract the reference to the wasm
object and the function index from the stack trace, and make it
available through all the APIs which process stack traces.
The javascript CallSite object now has the new methods isWasm(),
getWasmObject() and getWasmFunctionIndex(); the byte offset is
available via getPosition().
Function names of wasm frames should be fully functional with this
commit, position information works reliably for calls, but not for
traps like unreachable or out-of-bounds accesses.
