Move INIT_ARCH_EXT call from libm-test-support to libm-test-driver.

Browse Source 
libmvec tests involve calling INIT_ARCH_EXT during initialization then
CHECK_ARCH_EXT before testing each function to see if the processor
being used for testing supports the required instruction set
extensions.

After my refactoring of libm-test infrastructure, the INIT_ARCH_EXT
call is in libm-test-support.c, built only once per floating-point
type.  Now, in fact all definitions of this macro are empty, but given
that the definitions in sysdeps/x86_64/fpu/math-tests-arch.h are
conditional on REQUIRE_* macros defined in particular vector tests, it
seems more correct for the INIT_ARCH_EXT call to go instead in
libm-test-driver.c which gets built separately with those REQUIRE_*
macros properly defined.  This patch moves the call there.

Tested for x86_64 and x86.

	* math/libm-test-support.h: Do not include <math-tests-arch.h>
	here.
	* math/libm-test-support.c (libm_test_init): Do not call
	INIT_ARCH_EXT here.
	* math/libm-test-driver.c: Include <math-tests-arch.h>.
	(main): Call INIT_ARCH_EXT.
