* sysdeps/i386/fpu/e_rem_pio2f.c: Delete so that i386 uses the
	ieee754/flt-32 implementation.
	* sysdeps/i386/fpu/k_rem_pio2f.c: Likewise.
	* sysdeps/i386/fpu/s_cosf.S: Likewise.
	* sysdeps/i386/fpu/s_sincosf.S: Likewise.
	* sysdeps/i386/fpu/s_sinf.S: Likewise.

	* math/libm-test.inc (cos_test): Enable some large input tests for
	float as well
	(sin_test): Likewise.
	(sincos_test): Likewise.
	* sysdeps/i386/fpu/libm-test-ulps: Update.
