Actual Linux/sparc64 testing found that hundreds of sparcv9 test `F…

In hindsight this is no wonder: while
`compiler-rt/lib/asan/asan_mapping_sparc64.h` has support for the
Linux/sparc64 VA hole,

    AddressSanitizer: 64-bit SPARC/Linux port
```
there's nothing corresponding in `clang`.  Also, `gcc` disables 64-bit ASan
on Linux/sparc64, too.

So this patch disables `sparcv9` ASan testing in general.

Tested on `sparcv9-sun-solaris2.11` and `sparc64-unknown-linux-gnu`
