  tcg/aarch64: add ext argument to tcg_out_insn_3310

The new argument lets you pick uxtw or uxtx mode for the offset
register.  For now, all callers pass TCG_TYPE_I64 so that uxtx
is generated.  The bits for uxtx are removed from I3312_TO_I3310.

  tcg/aarch64: use 32-bit offset for 32-bit user-mode emulation

Thanks to the previous patch, it is now easy for tcg_out_qemu_ld and
tcg_out_qemu_st to use a 32-bit zero extended offset.  However, the
guest base register x28 must be the base and addr_reg must be the
index.

  tcg/aarch64: use 32-bit offset for 32-bit softmmu emulation

Similar to the same fix for user-mode, except this instance
occurs on the softmmu path.  Again, the tlb addend must be
the base register, while the guest address is the index.

  tcg/optimize: fix tcg_opt_gen_movi

Due to a copy&paste, the new op value is tested against mov_i32 instead
of movi_i32. The test is therefore always false. Fix that.
