fd4e77cf33
This patch accelerates complex division by passing `-complex-range=basic` to the frontend when the `-ffast-math` option is specified. This behavior is the same as `-fcomplex-arithmetic=basic`. A warning is issued if a different value is specified for `-fcomplex-arithmetic=`. The warning conditions will be unified with clang.
