The {WasmSharedModuleData} struct was introduced to hold data common to
all wasm instances belonging to the same module. The idea was to keep
"internal state" separate from the JS-facing {WasmModuleObject}. Since
this objective has no real value, and we already store some internal
data on the {WasmModuleObject}, this CL merges these two objects.

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).

The interface of {WasmCompiledModule} currently mostly receives and
provides handles to the contained data. Other interfaces don't (see
{object-macros.h}.
This leads to performance and memory overhead for chained accesses like
{instance->compiled_module()->shared()->script()}, because intermediate
accessors allocate Handles for no reason. It also breaks the
constraints that lower-case accessors should be trivial to execute, but
allocating a handle is not trivial (should not be done in a loop if not
needed).
It also silences gcmole errors, as documented in

This CL consolidates ownership of parameters used to compile code (which
we always specialize) in 2 places:
- ModuleEnv for compile-time data
- WasmCompiledModule for runtime data
The parameters in question are: memory size and start; globals start;
address of indirect function tables (and their signatures, respectively);
and address to be used for wasm call sites.
Ideally, we'd collapse this down to one place, however, we need
specialization data to survive serialization. We can achieve this we get off
the GC heap and use a different wasm code serializer.
The CL:
- removes aliasing of parts of the specialization data, and moves
to using ModuleEnv as a token of passing around compile-time data, instead
of a mixture of ModuleEnv, WasmInstance, and some other structures. ModuleEnv
is responsible for providing a consistent view of the specialization data,
e.g. valid memory sizes (multiples of page size), and matching sized function
tables and signatures.
- removes WasmInstance, as its data is now contained by ModuleEnv.
- removes ModuleBytesEnv. We now pass the wire bytes explicitly. They can't
always be assumed as present (e.g. streaming compilation), and probably more
refactoring may need to happen once streaming compilation lands and we
better understand our dependencies.

My goal was to move breakpoint API to native with minimal changes around, so on inspector side we use v8::debug::BreakpointId instead of String16, on v8::internal::Debug we use i::BreakPoint object instead of break point object created inside of debug.js.
There are a lot of opportunities how we can improve breakpoints (at least we can avoid some of linear lookups to speedup implementation) but I think that as first step we need to remove mirrors/debug.js APIs.
Drive by: debugger-script.js and usage of debugger context in inspector code base.

For functions declared in source code, the .toString() representation
will be an excerpt of the source code.
* For functions declared with the "function" keyword, the excerpt
starts at the "function" or "async" keyword and ends at the final "}".
The previous behavior would start the excerpt at the "(" of the
parameter list, and prepend a canonical `"function " + name` or
similar, which would discard comments and formatting surrounding the
function's name. Anonymous functions declared as function expressions
no longer get the name "anonymous" in their toString representation.
* For methods, the excerpt starts at the "get", "set", "*" (for
generator methods), or property name, whichever comes first.
Previously, the toString representation for methods would use a
canonical prefix before the "(" of the parameter list. Note that any
"static" keyword is omitted.
* For arrow functions and class declarations, the excerpt is unchanged.
For functions created with the Function, GeneratorFunction, or
AsyncFunction constructors:
* The string separating the parameter text and body text is now
"\n) {\n", where previously it was "\n/*``*/) {\n" or ") {\n".
* At one point, newline normalization was required by the spec here,
but that was removed from the spec, and so this CL does not do it.
Included in this CL is a fix for CreateDynamicFunction parsing. ')'
and '`' characters in the parameter string are no longer disallowed,
and Function("a=function(", "}){") is no longer allowed.

Implement stepping by remembering the current step action in the wasm
interpreter handle in WasmDebugInfo, and using it when continuing
execution in the interpreter.
The control flow is as follows: After module compilation, the user sets
a breakpoint in wasm. The respective function is redirected to the
interpreter and the breakpoint is set on the interpreter. When it is
hit, we notify all debug event listeners, which might prepare stepping.
When returning from these listeners, before continuing execution, we
check whether stepping was requested and continue execution in the
interpreter accordingly.
Stepping from Wasm to JS and vice versa will be implemented and tested
in a follow-up CL. Testing this requires breakpoints and stepping in
Wasm to be exposed via the inspector interface, such that we can write
an inspector test. This mixed JS-Wasm-execution is hard to set up in a
cctest.

The new object will hold information which is shared by all clones of a
WasmCompiledModule, e.g. the decoded asm.js offset table, and in the
future also breakpoints. From there, we can set them on each new
instantiation of any clone.
While already changing lots of the code base, I also renamed all
getters from "get_foo" to "foo", to conform to the style guide.
