​https://bugs.webkit.org/show_bug.cgi?id=147293

Patch by Sukolsak Sakshuwong <Sukolsak Sakshuwong> on 2015-07-28
Reviewed by Geoffrey Garen.

Implement WebAssembly module parser for WebAssembly files produced by pack-asmjs
<​https://github.com/WebAssembly/polyfill-prototype-1>. This patch only checks
the magic number at the beginning of the files. Parsing of the rest will be
implemented in a subsequent patch.
