c4c68e8d86 Fix crash in flowmap 
In 2fcc1ee72e, the following is apparantly added in order to mark any
number of undefined LUT inputs:

lut_a.append(RTLIL::Const(State::Sx, minlut - input_nodes.size()));

However this can only be done if the number of input nodes is less
than minlut.

This fixes #3317

e792bd56b7 flowmap: clean up terminology. 
* "map": group gates into LUTs;
  * "pack": replace gates with LUTs.

This is important because we have FlowMap and DF-Map, and currently
our messages are ambiguous.

Also clean up some other log messages while we're at it.
