This patch implements the following ACLE intrinsics:

  uint32_t __arm_vcx1_u32(int coproc, uint32_t imm);
  uint32_t __arm_vcx1a_u32(int coproc, uint32_t acc, uint32_t imm);
  uint32_t __arm_vcx2_u32(int coproc, uint32_t n, uint32_t imm);
  uint32_t __arm_vcx2a_u32(int coproc, uint32_t acc, uint32_t n, uint32_t imm);
  uint32_t __arm_vcx3_u32(int coproc, uint32_t n, uint32_t m, uint32_t imm);
  uint32_t __arm_vcx3a_u32(int coproc, uint32_t acc, uint32_t n, uint32_t m, uint32_t imm);
  
  uint64_t __arm_vcx1d_u64(int coproc, uint32_t imm);
  uint64_t __arm_vcx1da_u64(int coproc, uint64_t acc, uint32_t imm);
  uint64_t __arm_vcx2d_u64(int coproc, uint64_t m, uint32_t imm);
  uint64_t __arm_vcx2da_u64(int coproc, uint64_t acc, uint64_t m, uint32_t imm);
  uint64_t __arm_vcx3d_u64(int coproc, uint64_t n, uint64_t m, uint32_t imm);
  uint64_t __arm_vcx3da_u64(int coproc, uint64_t acc, uint64_t n, uint64_t m, uint32_t imm);

Since the semantics of CDE instructions is opaque to the compiler, the
ACLE intrinsics require dedicated LLVM IR intrinsics. The 64-bit and
32-bit variants share the same IR intrinsic.
