ac6c858d072016ad2c409f1593fa290ad0d87e11 testsuite: aarch64: Add zero-high-half tests for narrowing shifts
Add tests to verify that Neon narrowing-shift instructions clear the
top half of the result vector. It is sufficient to show that a
subsequent combine with a zero-vector is optimized away - leaving
just the narrowing-shift instruction.
