a4f0021f89 Update and copyedit README for rustc 
Lindsey pointed out that the location of librustsyntax was out-of-date,
so I fixed that; noticed a lot of other out-of-date info; and updated it.
I also obliterated all passive voice. Yay!

Closes #2382

e2d18c9a8a Remove an assertion from trans::base::iter_structural_ty 
I had put in an assertion that if the ty is a class, it doesn't have a dtor,
but that doesn't make sense, since this gets used to make take glue and
not just drop glue.

4f105e4025 In resolve, visit the path in an iface ref 
Necessary to resolve any type arguments in a ref to a parameterized
iface. This meant that, for example:

class A implements B<int> { ...

didn't work before, because the "int" in B's argument wasn't getting
visited, and thus wasn't getting resolved. Now it works.

Partially addresses Issue #2288, but I also want to check that class
ty params can appear as the type arguments to ifaces (for example,

class A<T> implements B<T> {...

should work.)

See the test case I added (issue-2316-c) for a concrete example.
issue-2316 also contains the originally reported test case. resolve
was using bitwise or instead of logical or when checking exports,
resulting in excessively eager evaluation. A one-line fix that took
six hours to isolate ;-)

2bb3b63ec4 Eliminate a copy in syntax::parse::new_parser_from_file 
Fixing a FIXME turned out to be pretty involved. I added an io function
that returns a unique boxed string (for the contents of a file) rather than
a string, and went from there. Also made the src field of codemap a unique
boxed string. This doesn't seem to make that much difference in amount of
allocation according to valgrind (disappointingly), but I also had to introduce
a copy somewhere else pending a new snapshot, so maybe that's it.

This alignment is the "preferred" alignment of a type, which is not

type into structures - that is the "ABI" alignment (in LLVM terms).

ABI alignment.

- fix various small bugs:
  - we never checked that iface types were compatible when casting
    to an iface with `as`
  - we allowed nonsense like int<int>
  - and more! (actually that may be it)

734166f41c Print out return type correctly in typestate error message 
In the "not all paths return" error message, typestate was printing
the AST type from the fn decl, not the ty::t type. This ended in tears
when the AST return type was "ty_infer". Now it looks up the function node
ID's type and uses util::ppaux::ty_to_str instead.

Closes #2163.

37b0549730 Add new syntax for patterns that match the head constructor only 
Adds a new kind of pattern C(*) where C is a constructor that may
have any number of fields. This pattern matches any value
constructed with C, without binding names for any of the fields.

Closes #1701.

b0074c5a92 Disallow rebinding / matching against consts in alts 
As per Issue #1193. Closes #1193.

I had to rename a few variables ("info" and "epsilon") to avoid
clashing with in-scope constants, which is responsible for all the
changes other than resolve and issue-1193.rs.
