Subject: Fix asm2wasm dead lock caused by empty modules.

This commit fixes an asm2wasm dead lock when asm2wasm is compiling an
empty module, i.e. a module without any functions.

Without this commit, worker threads are likely to leave `workerMain()`
and decrease `liveWorkers` early.  Consequently, `waitUntilAllReady()`
will never observe `liveWorkers == numWorkers`.
