      The recently added gcc.target/aarch64/advsimd-intrinsics/vrnd*.c tests cause
      failures due to accidentally running on non-ARMv8 hardware - the target check
      arm_v8_neon_ok is correct for compilation tests but should be arm_v8_neon_hw
      for execution tests.  Fix this and also change arm_v8_neon_hw to return
      true for AArch64 so these tests are run on AArch64 too.

    • Improve modes_tieable by returning true in more cases... · 61f17a5c
      Improve modes_tieable by returning true in more cases: allow scalar access
      within vectors without requiring an extra move.  Removing these moves helps
      the register allocator in deciding whether to use integer or FP registers on
      operations that can be done on both.  This saves about 100 instructions in the
      gcc.target/aarch64 tests.
      
      A typical example:
      
      	orr     v1.8b, v0.8b, v1.8b
      	fmov    x0, d0
      	fmov    x1, d1
      	add     x0, x1, x0
      	ins     v0.d[0], x0
      	orr     v0.8b, v1.8b, v0.8b
      
      after:
      
      	orr     v1.8b, v0.8b, v1.8b
      	add     d0, d1, d0
      	orr     v0.8b, v1.8b, v0.8b
      
          gcc/
      	* config/aarch64/aarch64.c (aarch64_modes_tieable_p):
      	Allow scalar/single vector modes to be tieable.
