Jonas Maebe c80fb6a20e * explicitly specify whether an llvm specification is a definition (= locally
defined) or a declaration (external symbol), instead of deriving it from
    from the bind of the tasmsymbol. The reason is that with module-level
    inline assembly, some locally implemented functions (in pure assembler)
    won't have an LLVM IR body
