  tcg/aarch64: Fix tcg_out_qemu_{ld, st} for guest_base == 0

In ffc6372851d8631a9f9fa56ec613b3244dc635b9, we swapped the guest
base to the address base register from the address index register.
Except that 31 in the base slot is SP not XZR, so we need to be
more intelligent about which reg gets placed in which slot.

  tcg/i386: omit a few REXW prefixes in softmmu code

When computing the TLB address we are likely to mask out the high
32-bits by using shr + and. We can use 32-bit instructions in that
case. This saves 2 bytes per TLB access.
