    [wasm][streaming] Check section order of code section · e4f07c09
    Clemens Backes authored
    The streaming decoder did not properly check the ordering of sections
    relative to the code section.
    This CL fixes that for both empty and non-empty code sections.
    The special path for empty code sections is not actually needed, so
    remove it to simplify code paths.
    
    Drive-by:
    1. Refactor the existing code for checking section ordering to make it
       more structured and readable.
    2. Ensure that we either call {DecodeCodeSection} or {StartCodeSection},
       but not both.
    3. Remove {set_code_section}, merge it into {StartCodeSection}.
    4. Simplify calls to {CalculateGlobalOffsets} (make them unconditional
       and remove one redundant one).
