888262b337 Allow operator overloading of the indexing operator 
The method `op_index` (which takes a single argument) is used for
this.

(Commit also includes lots of changes to remove '.'s that a git
merge messed up, or else it was monkeys.)

54f6bf57e6 remove align_mode and rewrite GEP_tup_like to align correctly 
Although the old version of GEP_tup_like was incorrect in some
cases, I do not believe we ever used it in an incorrect fashion.
In particular, it could go wrong with extended index sequences
like [0, 1, 3], but as near as I can tell we only ever use it
with short sequences like [0, i].

c3bc8fada8 Allow omission of the '.' after nullary tag patterns 
This commit allows patterns like:

alt x { some(_) { ... } none { } }

without the '.' after none. The parser suspends judgment about
whether a bare ident is a tag or a new bound variable; instead,
the resolver disambiguates.

This means that any code after resolution that pattern-matches on
patterns needs to call pat_util::normalize_pat, which consults
an environment to do this disambiguation.

In addition, local variables are no longer allowed to shadow
tag names, so this required changing some code (e.g. renaming
variables named "mut", and renaming ast::sub to subtract).

The parser currently accepts patterns with and without the '.'.
Once the compiler and libraries are changed, it will no longer
accept the '.'.

e1c50c4410 Don't evaluate discriminator value constants when parsing. 
Remove disr_val from ast::variant_ and always use ty::variant_info
when the value is needed.  Move what was done during parsing into
other passes, primary typeck.rs.  This move also correctly type checks
the disr. value expression; thus, fixing rustc --pretty=typed when
disr. values are used.

efb9df1ebd Make driver::session::session no longer an object 
Rather, it is now a struct where properties like opts are accessed
directly, and the error-reporting methods are part of a static impl
(with the same name as the type).

08abf8d37f Support explicit discriminant numbers on tag variants. 
Addresses issue #1393.

For now disallow disr. values unless all variants use nullary
contractors (i.e. "enum-like").

Disr. values are now encoded in the crate metadata, but only when it
will differ from the inferred value based on the order.

a7e1a35f88 Properly typecheck and compile invocations of generic methods. 
Aligning the type parameters of the ifaces, impls, and methods
correctly in typeck is almost brain surgery. Seems to work now for
everything I threw at it, but might still break in other corner cases.
