1393c3a3f4 Use a specialized string interner to reduce the need for owned strings 
&str can be turned into @~str on demand, using to_owned(), so for
strings, we can create a specialized interner that accepts &str for
intern() and find() but stores and returns @~str.

f30f54e9d0 librustc: Remove the concept of modes from the compiler. 
This commit does not remove `ty::arg`, although that should be
possible to do now.

17459d0bd3 rustc: Purge of HashMap, fixing segfaulting cases 
Various FIXME comments added around to denote copies which when removed cause
the compiler to segfault at some point before stage2. None of these copies
should even be necessary.

00f97b9fb0 Refactor the self-info so that the def-id is carried in ty_self() 
and the fn_ctxt doesn't need any self_info field at all.

Step towards fixing `fn(&self)` (cc #4846) to have a distinct
lifetime.

319eeb1c79 rename map -> oldmap and mark it as deprecated 
LinearMap is quite a bit faster, and is fully owned/sendable without
requiring copies. The older std::map also doesn't use explicit self and
relies on mutable fields.

0682ad0eb9 Finalize moves-based-on-type implementation. 
Changes:

- Refactor move mode computation
- Removes move mode arguments, unary move, capture clauses
  (though they still parse for backwards compatibility)
- Simplify how moves are handled in trans
- Fix a number of illegal copies that cropped up
- Workaround for bug involving def-ids in params
  (see details below)

Future work (I'll open bugs for these...):

- Improve error messages for moves that are due
  to bindings
- Add support for moving owned content like a.b.c
  to borrow check, test in trans (but I think it'll
  "just work")
- Proper fix for def-ids in params

Def ids in params:

Move captures into a map instead of recomputing.

This is a workaround for a larger bug having to do with the def-ids associated
with ty_params, which are not always properly preserved when inlining.  I am
not sure of my preferred fix for the larger bug yet.  This current fix removes
the only code in trans that I know of which relies on ty_param def-ids, but
feels fragile.

0046ed9462 Remove un-needed code for obsolete classes 
and rename "class" to "struct" everywhere possible (except local
vars, I was too lazy for that) -- that is why this commit is so
big.

No review, just dead code removal and renaming.

ef833d4101 Introduce a T_err type for type errors 
This allows more errors to be non-fatal, as per #1871.

I only went through and started changing span_fatal to span_err in
check.rs. There are probably more errors that could be made
non-fatal. So if you see derived type errors appearing from now on,
file a bug!
