Stale files in vhdl folder

[ggreif]

When iterating a design sometimes stale files remain in vhdl/* (and other) folders. It would be nice to have an extension to the synthesis commands :vhdl that clean out stale files.
Would :vhdl-clean or :vhdl -clean work?

We used to do this by default, but somehow this feature got dropped when we switched to supporting multiple backends. I prefer that cleaning up would be the default again.

So in interactive mode we would have: :vhdl [noclean], where the square brackets indicate that it is an optional argument.

In batch mode we would have -clash-noclean flag. So you'd say: clash --vhdl -clash-noclean <MODULE.hs>.

I'll implement this soon, probably by tomorrow already.

woot!

OK, slight change of what I said earlier. There's one static flag: -clash-noclean, which tells CLaSH NOT to clean up existing HDL files, and it applies to both the interactive and the batch modes. That is, there is no additional option for the interactive :vhdl command.

Being a static flag, it can only be supplied when you start the clash compiler. So you cannot do :set -clash-noclean in interactive mode.
