2023-03-13target/arm: Avoid tcg_const_ptr in handle_revRichard Henderson
Here it is not trivial to notice first initialization, so explicitly zero the temps. Use an array for the output, rather than separate tcg_rd/tcg_rd_hi variables.

While this enumerator has been present since the first commit, it isn't ever used. The first actual use of round-to-odd came with SVE, which currently uses float_round_to_odd instead of the arm-specific enumerator.
