cfa09d35a3 Revert "allow fn exprs to omit arg types"

1ba4ca4c4a allow fn exprs to omit arg types 
also, avoid using type variables for fn args with omitted types
unless necessary.  This will be important for bound regions in
fn types.

d0d71838cd Mention missing constructor when complaining about inexhaustive top-level pattern 
It previously, uselessly, only pointed out the constructor when the
inexhaustive pattern was nested in some other pattern.

2db4259b35 Stop inferring bot/static when types/regions are unconstrained. 
Also, some other changes that came up along the way:
- add a 'blk' region for the current block.
- detect unused type/region variables.

825fd1808e lots of work to make iface/impls parameterized by regions 
- paths can now take region parameters, replacing the dirty hack
  I was doing before of abusing vstores.  vstores are now a bit
  of a hack though.

- fix various small bugs:
  - we never checked that iface types were compatible when casting
    to an iface with `as`
  - we allowed nonsense like int<int>
  - and more! (actually that may be it)
