Add tests for v[r]addhn_high and v[r]subhn_high Neon intrinsics.
Since these intrinsics are only supported for AArch64, these tests
are restricted to only run on AArch64 targets.
gcc/testsuite/ChangeLog:
2021-03-02 Jonathan Wright <jonathan.wright@arm.com>
* gcc.target/aarch64/advsimd-intrinsics/vXXXhn_high.inc:
New test template.
* gcc.target/aarch64/advsimd-intrinsics/vaddhn_high.c:
New test.
* gcc.target/aarch64/advsimd-intrinsics/vraddhn_high.c:
New test.
* gcc.target/aarch64/advsimd-intrinsics/vrsubhn_high.c:
New test.
* gcc.target/aarch64/advsimd-intrinsics/vsubhn_high.c:
New test.
