fpu: Rename float_flag_output_denormal to float_flag_output_denormal_flushed

Our float_flag_output_denormal exception flag is set when
the fpu code flushes an output denormal to zero. Rename
it to float_flag_output_denormal_flushed:
 * this keeps it parallel with the flag for flushing
   input denormals, which we just renamed
 * it makes it clearer that it doesn't mean "set when
   the output is a denormal"

Commit created with
 for f in `git grep -l float_flag_output_denormal`; do sed -i -e 's/float_flag_output_denormal/float_flag_output_denormal_flushed/' $f; done
