we should not add explicit declaration there.

arm_neon.h contains those prototype already. they will be available if the
compiler configuration is with related builtin predefine, for example __ARM_FEATURE_CRYPTO.

so, actually, if there is any warning when compile these test programs, they are expected,
and we rely on these warnings to check whether certain features are available.

previously, I only verified on arm-none-linux-gnueabi cross check, so have not exposed
these regressions.

no verified on arm-none-linux-gnueabihf, regression gone away on arm directory.

make check RUNTESTFLAGS="aapcs.exp neon.exp acle.exp simd.exp arm.exp"

ok for trunk?

gcc/testsuite/

         * lib/target-supports.exp
         (check_effective_target_arm_crypto_ok_nocache): Remove declaration for
         vaeseq_u8.
         (check_effective_target_arm_neon_fp16_ok_nocache): Remove declaration for
         vcvt_f16_f32.
         (check_effective_target_arm_neonv2_ok_nocache): Remove declaration for
         vfma_f32.

 I had also missed the vaes and vfma turning on by default by this
change. This is OK.
