[PATCH] D41010: [orc][cmake] Check if 8 byte atomics require libatomic for unittest

[Simon Dardis via Phabricator via llvm-commits]

https://reviews.llvm.org/rL319838 introduced SymbolStringPool which uses 8 byte atomics for
reference counters. On systems which do not support such atomics
natively such as MIPS32, explicitly add libatomic as one of the
libraries for SymbolStringPool's unittest.
