This relands commit 13dd65b3a1a3ac049b5f3a9712059f7c61649bea. The original commit contained a test, which failed when compiled for a MACH-O target. This patch changes the test to run for x86_64-linux instead of `%itanium_abi_triple`, to avoid having invalid syntax for MACH-O sections. The patch itself does not care about section attribute syntax and a x86 backend does not even need to be included in the build. Differential Revision: https://reviews.llvm.org/D102693
