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.

* gcc.target/aarch64/narrow_zero_high_half.c: New test.
