  compiler: Fix compiler crash introduced by OTP-15952

An assertion in code generation would fail when the common exit
block was ?BADARG_BLOCK, as some operations expect to always "fail"
directly to that block (= throw an exception) and we had inserted
a dummy block in between.

Other operations could also get funny fail labels, jumping to
blocks that immediately jumped to {f,0}, but these were all cleaned
up by beam_jump, sweeping the bug under the rug.
