[Driver] Default to -mv8plus on 32-bit Solaris/SPARC (#150176)
While investigating PR #149990, I noticed that while both the Oracle
Studio compilers and GCC default to `-mv8plus` on 32-bit Solaris/SPARC,
Clang does not.
This patch fixes this by enabling the `v8plus` feature.
Tested on `sparcv9-sun-solaris2.11` and `sparc64-unknown-linux-gnu`.
