985ef59efd Make for loops alias the vec elements, rather than copy them 
The alias analysis was already assuming that it worked like this.

139b1d1b31 Get rid of some unused upcalls 
I guess these became obsolete when the communication stuff moved into
the stdlib.

e57435f68b Don't put 0-length array in the lltype of an arg-less variant 
This seems to confuse LLVM in some very specific situations.

9946e467ff Export tag discriminants even for single-variant tags 
I don't know exactly what's going on but this optimization is giving
me problems with the check-fast runner. I also don't see how it is
correct for external tags.

b5f9053423 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!

bdd0417cec Handle if-check with no else correctly in typestate 
Propagate the if-check constraint into the consequent even when
there's no else branch. (Oops!)

786963d33d Add a constraint in trans 
Experimenting with adding typestate constraints in the compiler.
Added a constraint to GEP_tag that says the variant index is in
bounds. Added necessary checks.

fb196e6ef1 Make alias analysis properly recognize closures in call position

6ba4eacddf Make resolve recognize upvars 
Upvars are now marked with def_upvar throughout, not just when going
through freevars::lookup_def. This makes things less error-prone. One
thing to watch out for is that def_upvar is used in `for each` bodies
too, when they refer to a local outside the body.

2d1dec78e7 Move mutability checking into its own pass. 
Having it in the alias pass was slightly more efficient (finding
expression roots has to be done in both passes), but further muddled
up the already complex alias checker.

Also factors out some duplication in the mutability-checking code.
