Update i386 libm-test-ulps.

When testing changes to i386 libm functions (that are shadowed for
i686 builds by i686 versions) recently, I saw that the plain i386
libm-test-ulps (as opposed to the i686 multiarch version) needed
updating for tests that had been added since it was last updated.
This patch updates it accordingly.

	* sysdeps/i386/fpu/libm-test-ulps: Update.
