When guest_base != 0, we were not coordinating the usage of TCG_REG_TMP0 as base properly, leading to a previous zero-extend of the input address being discarded. Shuffle the alignment check to the front, because that does not depend on the zero-extend, and it keeps the register usage clear. Set base after each step of the address arithmetic instead of before. Return the base register used from tcg_out_tlb_load, so as to keep that register choice localized to that function.
