target-ppc: fix wrong NaN tests
Some tests in FPU emulation code were wrongly using float64_is_nan() before commit 185698715dfb18c82ad2a5dbc169908602d43e81, and wrongly using float64_is_quiet_nan() after. Fix them by using float64_is_any_nan() instead. Reviewed-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
