…mar (pythonGH-21020) `GET_INVALID_TARGET` might unexpectedly return `NULL`, which if not caught will cause a SEGFAULT. Therefore, this commit introduces a new inline function `RAISE_SYNTAX_ERROR_INVALID_TARGET` that always checks for `GET_INVALID_TARGET` returning NULL and can be used in the grammar, replacing the long C ternary operation used till now. (cherry picked from commit 6c4e0bd)
