[Qemu-devel] [PULL 07/24] target/arm: Tidy conditions in handle_vec_simd_shri

[Peter Maydell]

From: Richard Henderson <address@hidden>

The (size > 3 && !is_q) condition is identical to the preceeding test
of bit 3 in immh; eliminate it.  For the benefit of Coverity, assert
that size is within the bounds we expect.
