5bdb13297f [wasm] merge js constants file in module-builder
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.

da03262e4c [wasm] Fix for exporting imported mutable globals
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).

2747d0e6da [wasm] Fix some bugs in mut global implementation
* 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.

6a50560650 [wasm] Implement WebAssembly.Global import/export
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.
