[XRay][ARM32][AArch64] Fix unstable FDR tests on weak-ordering CPUs
Summary: Change from `compare_exchange_weak()` to `compare_exchange_strong()` where appropriate, because on ARM ( http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15-full/builds/3190 , http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15-full/builds/3191 ) and AArch64 ( http://lab.llvm.org:8011/builders/clang-cmake-aarch64-42vma/builds/3900 ) it fails even in single-threaded scenarios.
