f76e28aa1c Allow consts' LLVM types to depend on their initializers.
Loosening the connection between the LLVM type and the Rust type
is necessary to use non-nullary enum constructors as const initializers,
because the const needs to be initialized with data of the actual type of
the variant in question, which is (generally) not the same as the u8
array in the `type_of` type.

Thus, referring to a const now requires casting the LLVM global to the
expected pointer type instead of using it as-is.

a0c2a9b743 librustc: Implement a #[no_mangle] attribute to suppress name mangling. r=brson
This is very helpful for SDL, as SDL wants you to define a function named
`SDL_main`.

42095221f4 Properly suppress derived type error messages
Previously, the typechecker suppressed many but not all errors,
by suppressing errors where the actual type was either ty_err, or
a function type whose result was ty_err. Added a has_ty_err flag
to the type flags so as to suppress errors for any types involving
ty_err.

737e115646 mode: reset mode on entry to fn body.
This is an interim fix to address the "Beware!" unsoundness.  I have a
more comprehensive rewrite of mode.rs in the pipeline.

2b92962aa2 A collection of refactorings that I found it hard/tiresome to divide:
- Make `extern fn()` assignable to any closure type, rather than
  a subtype.
- Remove unused int_ty_set and float_ty_set
- Refactor variable unification and make it more DRY
- Do fn sub/lub/glb on the level of fn_sig
- Rename infer::to_str::ToStr to infer::to_str::InferStr
- Capitalize names of various types
- Correct hashing of FnMeta
- Convert various records-of-fns into structs-of-fns.  This is both
  eliminating use of deprecated features and more forwards compatible
  with fn reform.

2d1ce01a8a Suppress error messages about function types whose result is ty_err
Ideally we would suppress error messages involving any types that
contain ty_err, but that's awkward to do right now.

921393c568 Change the self def_id to a self_info in typeck, and inherit
That is, treat `self` as if it has dynamic scope. This seems to
be harmless, and prevents an ICE as per #3563

have ty_err as a sub-component, but this works for now.
