Description JF Bastien 2016-12-23 10:13:44 PST
The WasmB3IRGenerator's addCall doesn't need to generate a patchpoint for imports (toJS and toWasm) because they all get generated before the B3 compilation starts. Plan the goes through m_unlinkedWasmToWasmCalls and links them after all B3 compilation is done, which is extra work we didn't need to do.

This is a slight optimization and requires improving WasmB3IRGenerator, which I'll do later. I'm leaving two FIXMEs for now.
