[PATCH] D34158: to support gcc 4.8 (and newer) compatibility on Linux, preinclude <stdc-predef.h>

[Melanie Blower via Phabricator via cfe-commits]

mibintc added a comment.

Here's  a modified revision which checks if stdc-predef.h exists before adding a -include option to that file.  this is only for Linux using gcc 4.8 and higher.  Several tests needed to be fixed because of this change - i fixed them by suppressing the preinclude using ffreestanding or nostdinc.  Also i need to change about 10 clang/tools/extra/test/clang-tidy tests.  Those test changes aren't in this patch.  Please tell me: what's the correct procedure for getting those tests reviewed? Thanks Fedor for your reviews!
