2aac43d809 Simplify trans::new_fn_ctxt_w_id
It was still living in the pre-decent-type-inference era.

6d3dd0e48c Try harder still to generate fewer landing pads
Scopes that don't have cleanups don't need their own landing pads

This takes the optimized rustc bin from 4.7MB to 4.4

b8e31ac469 Try a little harder to avoid creating new landing pads
It's only when we add or revoke cleanups involving immediates that we need a
new landing pad for the scope.

Trims 5K off the optimized rustc bin

fc6b7c8b38 Reformat for new mode syntax, step 1
Long lines were fixed in a very crude way, as I'll be following up
with another reformat in a bit.

4be7e1e5cd Pass all arguments by reference, make immut alias mode equiv to value
Arguments that can't be safely referenced will be implicitly copied.

(Warnings for expensive copies will be forthcoming.)

This will allow us to get rid of most of the ampersands in function
signatures. See [1].

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!

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.

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.
