testsuite: arm: Update expected asm in armv8_2-fp16-neon-2.c

With the changes in r15-1579-g792f97b44ff, the test_vmul_n_16x8 function
does not contain any vdup.16 q* r* instruction with -mfloat-abi=softfp.

The differnce between r15-1578-g5185274c76c and r15-1579-g792f97b44ff
with -mfloat-abi=softfp for the function is:
        .global test_vmul_n_16x8
        .syntax unified
        .arm
        .type   test_vmul_n_16x8, %function
 test_vmul_n_16x8:
        @ args = 4, pretend = 0, frame = 0
        @ frame_needed = 0, uses_anonymous_args = 0
        @ link register save eliminated.
        vmov    d16, r0, r1  @ v8hf
        vmov    d17, r2, r3
-       ldrh    r3, [sp]        @ __fp16
-       vdup.16 q9, r3
+       vld1.16 {d18[], d19[]}, [sp]
        vmul.f16        q8, q9, q8
        vmov    r0, r1, d16  @ v8hf
        vmov    r2, r3, d17
        bx      lr
        .size   test_vmul_n_16x8, .-test_vmul_n_16x8

gcc/testsuite/ChangeLog:

	* gcc.target/arm/armv8_2-fp16-neon-2.c: Expect 3 vdup.16 q* r*
	when in arm_hf_eabi else 2.
