TCG: fix copy propagation
Copy propagation introduced in 22613af4a6d9602001e6d0e7b6d98aa40aa018dc
considered only global registers. However, register temps and stack
allocated locals must be handled differently because register temps
don't survive across brcond.
Fix by propagating only within same class of temps.
