[PATCH] D108917: [PowerPC] Define __powerpc and __PPC macros

[Chris Bowler via Phabricator via cfe-commits]

cebowleratibm added a comment.

The XL compiler only defined this weird form of the macros on AIX, but not on the XL Linux on Power compiler.  I think it's preferable that we define these macros only on AIX and in the source/commit messages indicate that we're only doing so for AIX XL C/C++ compatibility.  Users should prefer the __PPC__ and __powerpc__ macros.
