bjaideep 8071e21ce5 PPC/s390: [wasm] Separate compilation from instantiation 
Port c1d01aea11

Original commit message:

    Compilation of wasm functions happens before instantiation. Imports are linked afterwards, at instantiation time. Globals and memory are also
    allocated and then tied in via relocation at instantiation time.

    This paves the way for implementing Wasm.compile, a prerequisite to
    offering the compiled code serialization feature.

    Currently, the WasmModule::Compile method just returns a fixed array
    containing the code objects. More appropriate modeling of the compiled module to come.

    Opportunistically centralized the logic on how to update memory
    references, size, and globals, since that logic is the exact same on each
    architecture, except for the actual storing of values back in the
    instruction stream.
