5ca4fdfc98 Convert trans_tuple_struct to trans::adt. 
Surely this cannot be the best way to get the type.

ca450e345f Move trans_enum_variant to trans::adt. 
As a result, trans_enum_variant no longer cares what kind of enum it's
dealing with, so the "degen" parameter goes away in a bunch of places.

bb689c09f5 Convert const ADT construction to trans::adt. 
Also converts const cast-from-enum, because it used the same routine to
get the discriminant as what's renovated to construct the enums.

Also fixes ICE on struct-like variants as consts, and provides a slightly
less bad ICE for functional-update-like struct expressions in consts.

2a028c5ab8 Convert newtype "dereference" to trans::adt. 
Note that in the ByValue case (which can't happen? yet?) we're still
effectively bitcasting, I think.  So this change adds a way to assert
that that's safe.

Note also, for future reference, that LLVM's instcombine pass will turn
a bitcast into a GEP(0, 0, ...) if possible.

a5030e7615 Wrap const structs in as many LLVM structs as the non-const case. 
This, like the previous change for unit-like enums, is only necessary
until everything is fully converted to use trans::adt.

e09a843973 Handle unit-like types specially. 
This change remains separate from the addition of adt.rs, even though
it's necessary for compatibility with pre-trans::adt representation,
to serve as an example of a change to the representation logic.

7b2b4faba8 Add a test for enum discriminant range overflow. 
It causes an LLVM assertion for every host/target word-size combination
on incoming at the time of this writing.

626ad484fe Unified algebraic datatype representation implementation, initial version. 
Later changes on this branch adapt the rest of rustc::middle::trans
to use this module instead of scattered hard-coded knowledge of
representations; a few of them also have improvements or cleanup for
adt.rs (and many added comments) that weren't drastic enough to justify
changing history to move them into this commit.

8c3728f839 auto merge of #5125 : nikomatsakis/rust/issue-4846-lifetime-defaults, r=nikomatsakis 
Work towards #4846.

- Institute new region defaults where all omitted regions get a fresh lifetime.
- Require explicit region names except in functions.
- Fix a bug in region parameterization inference.  I've been putting this off because it will not be important when we remove RP inference in favor of explicit declarations, but then it was blocking this patch.
