Both ARM and AArch64 have defined some SIMD data types in arm_neon.h, but we don't have a test case for passing them and returning them in inferior call. This test also covers passing and returning homogeneous short vector aggregate (defined by AArch64 ABI document) in inferior call too. gdb/testsuite: * gdb.arch/arm-neon.exp: New. * gdb.arch/arm-neon.c: New.
