| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This pass is a proper subset of opt_rmdff, which is called by opt, which is called by every synth flow in the coarse part. Thus, it never actually does anything and can be safely removed.

| |_|/ / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Detect the places in the $alu where the carry bit is constant (due to const A[i] == B[i] ^ BI) and split it into smaller $alu at these points. Also, make the existing const-carry detection for low bits more generic (now handles cases where both BI and CI are constant, but not equal to one another). Fixes #1912.
