Fix typo in preprocessor conditional
m68k: update libm test ULPs
Add CFI to x86 ceil / floor / trunc (bug 16681).

This patch adds CFI to the sysdeps/i386/fpu/ implementations of ceil,
floor and trunc functions, for consistency with other x86 .S files in
glibc which have CFI for stack adjustments.

Tested x86.
