nios2: define tcg_env 



This should be done by all target and, since commit 53f6672b
("gen-icount: use tcg_ctx.tcg_env instead of cpu_env", 2017-06-30),
is causing the NIOS2 target to hang.

This is because the test for "should I exit to the main loop"
was being done with the correct offset to the icount decrementer,
but using TCG temporary 0 (the frame pointer) rather than the
env pointer.
