eafb6789a2 Stop creating function pairs for static functions
These are now called directly. When taking their value, a null pointer is added
to create a pair.

51dae63c44 Make most of the compiler aware of return-by-reference
tyencode/tydecode still don't know about it. return_ref will be extended to take
arguments anyway.

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].

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!

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.

c9c5ee252a Implement non-internal ivecs
Vectors are now similar to our old, pre-internal vectors, except that
they are uniquely owned, not refcounted.

Their name should probably change too, then. I've renamed them to vec
in the runtime, will do so throughout the compiler later.
