    jit: Fix accidentally-harmless type confusion
    
    In 2a0faed9d702, which added JIT compilation support for expressions, I
    accidentally used sizeof(LLVMBasicBlockRef *) instead of
    sizeof(LLVMBasicBlockRef) as part of computing the size of an allocation. That
    turns out to have no real negative consequences due to LLVMBasicBlockRef being
    a pointer itself (and thus having the same size). It still is wrong and
    confusing, so fix it.
    
    Reported by coverity.
