[PULL 02/28] target/arm: Diagnose UNALLOCATED in disas_simd_two_reg_misc_fp16

[Peter Maydell <peter.maydell@linaro.org>]

From: Richard Henderson <richard.henderson@linaro.org>

This fprintf+assert has been in place since the beginning.
It is prior to the fp_access_check, so we're still good to
raise sigill here.
