[KAWASHIMA Takahiro via cfe-commits]

If you type option names in the currnet Clang Compiler User's Manual, you'll see:

```console
$ clang -fnobasic-block-address-map -fnounique-internal-linkage-names -f-split-lto-unit test.c 
clang: error: unknown argument '-fnobasic-block-address-map'; did you mean '-fno-basic-block-address-map'?
clang: error: unknown argument '-fnounique-internal-linkage-names'; did you mean '-fno-unique-internal-linkage-names'?
clang: error: unknown argument '-f-split-lto-unit'; did you mean '-fsplit-lto-unit'?
```
