[ARM,CDE] Implement predicated Q-register CDE intrinsics
Summary:
This patch implements the following CDE intrinsics:
T __arm_vcx1q_m(int coproc, T inactive, uint32_t imm, mve_pred_t p);
T __arm_vcx2q_m(int coproc, T inactive, U n, uint32_t imm, mve_pred_t p);
T __arm_vcx3q_m(int coproc, T inactive, U n, V m, uint32_t imm, mve_pred_t p);
T __arm_vcx1qa_m(int coproc, T acc, uint32_t imm, mve_pred_t p);
T __arm_vcx2qa_m(int coproc, T acc, U n, uint32_t imm, mve_pred_t p);
T __arm_vcx3qa_m(int coproc, T acc, U n, V m, uint32_t imm, mve_pred_t p);
The intrinsics are not part of the released ACLE spec, but internally at
Arm we have reached consensus to add them to the next ACLE release.
