[PULL 22/38] tcg/tci: Push opcode emit into each case


From: Richard Henderson
Subject: [PULL 22/38] tcg/tci: Push opcode emit into each case
Date: Wed, 17 Mar 2021 09:34:28 -0600

We're about to split out bytecode output into helpers, but
we can't do that one at a time if tcg_out_op_t is being done
outside of the switch.
