This is a restricted alternative to D91605 <https://reviews.llvm.org/D91605> which only works on Solaris 11.4 SRU 10+, but would break the build on Solaris 11.3 and Illumos which lack `dlpi_tls_modid`.

Apart from that, the patch is trivial.  One caveat is that the `sanitizer_common` and `asan` tests need to be linked explicitly with `ld -z relax=transtls` on Solaris/amd64 since the archives with calls to `__tls_get_addr` are linked in directly.

Tested on `amd64-pc-solaris2.11`, `sparcv9-sun-solaris2.11`, and `x86_64-pc-linux-gnu`.
