We noticed that almost every call site were loading both files,
the split isn't necessary anymore.
In some message tests, removed the absolute line number to allow future
changes.

Mutable globals are stored in the instance differently, so they must be
exported differently as well.
Also fix a counting bug that occurred when a module contained a global
and an imported mutable global (CalculateGlobalOffsets is called
twice).

* If the mutability of the global object doesn't match the module, then
it should throw a LinkError.
* There was a missing `return` when importing a Number as a mutable
global.
* All globals were being exported as immutable.
* Attempting to set the value of an immutable global should throw a
TypeError.
* The length of the setter function should be 1.

The new spec has two arguments, the first is the global descriptor, and
the second is the initial value:
new WebAssembly.Global({type: i32}, 42);
If the initial value argument is omitted, the value is set to 0.

The WasmInstanceObject stores two new arrays:
- imported_mutable_globals_buffers_: a FixedArray of all the imported
globals' array buffers.
- imported_mutable_globals: a calloc'd array of Addresses pointing to
the mutable global in its array buffer.
When accessing the global, the generated code looks up the address in
imported_mutable_globals to find where to load/store.

The mutable-globals proposal spec allows importing as Numbers or
WebAssembly.Global values, but always exports as WebAssembly.Global.
Since the value is always boxed, we can also import/export i64 values.
This CL also includes support for export of mutable globals. Since the
underlying ArrayBuffer that stores the global's value is shared between
the module and the WebAssembly.Global object, all that needs to be done
is remove the validation check.
