From 4851a949b4cd1f280b56a728c784aaa85e51124c Mon Sep 17 00:00:00 2001
From: Richard Henderson <rth@twiddle.net>
Date: Fri, 9 Mar 2012 12:38:23 -0800
Subject: Make inline __isnan, __isinf_ns, __finite generic.

For code generation to stay identical on x86_64, this requires that
we define the fp word manipulation macros before including the
generic header.
