Implement the ConstantPoolIndex instruction for WebAssembly files generated by pack-asmjs <https://github.com/WebAssembly/polyfill-prototype-1>. This will make it easier to write tests for WebAssembly patches. Currently, we cannot use the same large numbers more than once in a test, because pack-asmjs will put them in the constant pool.
The ConstantPoolIndex instruction has been implemented in https://bugs.webkit.org/show_bug.cgi?id=148791
Fixed in http://trac.webkit.org/changeset/189405
