Blocks (or statements involving blocks) that end in a semicolon are no

to be an expression block, but now is a statement block:

Add a constraint to trans::type_of

trans::type_of now has a constraint saying that its type argument
is statically sized. This eliminates the "impossible happened" case
in type_of. Yay!
I note that this change decreased translation time for stage2/rustc
from 16.1 s to 14.0 s. I also think many of the remaining checks
could be eliminated with some mildly clever use of constrained types
and further preconditions. Future work!
