Create WebAssembly functions
https://bugs.webkit.org/show_bug.cgi?id=148373

Patch by Sukolsak Sakshuwong <sukolsak@gmail.com> on 2015-08-28
Reviewed by Filip Pizlo.

Source/JavaScriptCore:

Create functions from WebAssembly files generated by pack-asmjs
<https://github.com/WebAssembly/polyfill-prototype-1>.
WebAssembly functions created by this patch can only return 0.
Actual code generation will be implemented in subsequent patches.

This patch introduces WebAssemblyExecutable, a new subclass of
ExecutableBase for WebAssembly functions. CodeBlocks can now have
an owner that is not a ScriptExecutable. This patch changes the
return type of CodeBlock::ownerExecutable() from ScriptExecutable*
to ExecutableBase*. It also changes code that calls ScriptExecutable's
methods on CodeBlock::ownerExecutable() to use
CodeBlock::ownerScriptExecutable(), which does jsCast<ScriptExecutable*>.

Since ownerScriptExecutable() is called from WebCore and it uses
jsCast<ScriptExecutable*>, this patch needs to export
ScriptExecutable::info(). This should fix the build error in
