https://reviews.llvm.org/D157280 enabled `-fprofile-update` for `-fprofile-generate`, but omitted adding `-latomic` to the linker command on AIX. This omission causes linking to fail due to an undefined symbol. This patch fixes the link error. Reviewed By: w2yehia Differential Revision: https://reviews.llvm.org/D159137
