tcg/arm: Adjust constraints on qemu_ld/st Always reserve r3 for tlb softmmu lookup. Fix a bug in user-only ALL_QLDST_REGS, in that r14 is clobbered by the BLNE that leads to the misaligned trap. Remove r0+r1 from user-only ALL_QLDST_REGS; I believe these had been reserved for bswap, which we no longer perform during qemu_st.

tcg/arm: Add host vector framework Add registers and function stubs. The functionality is disabled via use_neon_instructions defined to 0. We must still include results for the mandatory opcodes in tcg_target_op_def, as all opcodes are checked during tcg init.
