[PATCH] D122377: [PowerPC] Support 16-byte lock free atomics on pwr8 and up

[Hubert Tong via Phabricator via cfe-commits]

hubert.reinterpretcast added a comment.

I am not sure that the choice of `isOSBinFormatELF` to (afaik) primarily scope this change from affecting AIX (where we know the library calls are not implemented to be lock-free yet) is better than alternative where the condition is for little-endian mode or specifically for not AIX.
