[PATCH] D153576: [Headers] Fix up some conditionals

[Craig Topper via Phabricator via cfe-commits]

craig.topper added a comment.

The mulx function being 32-bit mode only is also true in gcc. It probably won't generate a mulx instruction on x86-64. Maybe that's why it was 32-bit only? But it should still be functionally correct.
