Since the test uses __sync_fetch_and_add, add a requirement for target to support atomic operations on int and long types.
This fixes a spurious test failure on pru-unknown-elf, which lacks atomic ops. The test still passes on x86_64-linux-gnu. Pushed to trunk as obvious. gcc/testsuite/ChangeLog: * g++.dg/lto/pr47333_0.C: Require target that supports atomic operations on int and long types.
