PPC/s390: [wasm] Lazy compilation for asm.js

Port 4f3e168cf9e2ca22c5be354d7ae17f5f38943070

Original Commit Message:

    This CL adds general lazy compilation support to WebAssembly, according
    to the design described in the design doc (see referenced bug).

    It's not used currently, but I tested locally that all tests succeed if
    I enable it by default.

    With a later CL, we will enable lazy compilation by default for
    validate-asm: https://chromium-review.googlesource.com/451318
