/**
* Create an MCJIT execution engine for a module, with the given options. It is
* the responsibility of the caller to ensure that all fields in Options up to
* the given SizeOfOptions are initialized. It is correct to pass a smaller value
* of SizeOfOptions that omits some fields, and it is also correct to set any
* field to zero. The canonical way of using this is:
*
* LLVMMCJITCompilerOptions options;
* memset(&options, 0, sizeof(options));
* ... fill in those options you care about
* LLVMCreateMCJITCompilerForModule(&jit, mod, &options, sizeof(options), &error);
*
* Note that this is also correct, though possibly suboptimal:
*
* LLVMCreateMCJITCompilerForModule(&jit, mod, 0, 0, &error);
