Fix use-after-free on -DUSE_EMBED_CI=0
On -DUSE_EMBED_CI=0, there are more GC allocations and the old code
didn't keep old_operands[0] reachable while allocating. On a Debian
based system, I get a crash requiring erb under GC stress mode. On
macOS, tool/transcode-tblgen.rb runs incorrectly if I put GC.stress=true
as the first line.
