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.

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!

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.

e412652f00 Make GEP_tag take a uint instead of an int

c1ba28c777 Glob-import trans_build in other trans files
The capitalization already prevents name clashes. Being able to refer to the
bitcode-construction primitives directly makes the code cleaner.

b9112525ba Move to a more lightweight builder system
You now do

    bld::Ret(bcx, someval)

where you used to say

    bcx.build.Ret(someval)

Two fewer boxes are allocated for each block context, and build calls
no longer go through a vtable.

152cbaade7 Move functions from syntax::ast to syntax::ast_util

7d08678b74 Implement pattern guards
The syntax is

    alt x {
        mypat where mycond { ... }
    }

The condition may refer to any of the variables bound by the pattern.
When a guard fails, pattern-matching continues with the next pattern.

e0985c1060 Handle alt on a _|_ - typed value
Return the result of the discriminant from trans_alt,
rather than nil, in the _|_ case. This was breaking the
enclosed test case (alt-bot-2) when optimization was disabled.

731797d075 In trans, don't assume both sides of a binop have the same type
This was at least partially responsible for Issue 777.

    The only solution I can think of is for trans to just not generate
    code for a comparison if one or both sides has type _|_. Since
    that means evaluating that subexpression diverges, it should be ok
    to never do the comparison. Actually generating code for the
    comparison would trip an LLVM assertion failure.

6c9b90d06a Be a little more clever about picking columns to match on in trans_alt
This should result in slightly more efficient matching of 'complex'
patterns with multiple discriminants in them.

f8fa574864 Copy locals created by destructuring on the content of a box
This is required so that assigning to these locals doesn't clobber
the content of the box.

(A possible optimization would be to only do this copying for
locals that actually are assigned to.)

985c32ef4c Partially implement destructuring locals
You can now say

    let {bcx, val} = some_result_returner();

Similar for loop variables. Assigning to such variables is not safe
yet. Function arguments also remain a TODO.
