Instead of the GNU extension `SHF_GNU_RETAIN`, Solaris provides equivalent functionality with `SHF_SUNW_NODISCARD`. This patch implements the necessary support. Tested on `sparcv9-sun-solaris2.11`, `amd64-pc-solaris2.11`, and `x86_64-pc-linux-gnu`. Differential Revision: https://reviews.llvm.org/D107955
