    aarch64: introduce partial AdvSIMD vector modes

changed gcc.dg/vect/complex/bb-slp-complex-mla-half-float.c to:

-/* { dg-final { scan-tree-dump "Found COMPLEX_FMA" "slp1"  { xfail *-*-* } } } */
+/* { dg-final { scan-tree-dump "Found COMPLEX_FMA" "slp1" { xfail arm*-*-* } } */

The end brace was missing.  Add the missing end brace to fix it.

	PR testsuite/125489
	* gcc.dg/vect/complex/bb-slp-complex-mla-half-float.c: Add the
	missing end brace.
