eb4d39e1fe libstd: Remove "dual impls" from the language and enforce coherence rules. r=brson 
"Dual impls" are impls that are both type implementations and trait
implementations. They can lead to ambiguity and so this patch removes them
from the language.

This also enforces coherence rules. Without this patch, records can implement
traits not defined in the current crate. This patch fixes this, and updates
all of rustc to adhere to the new enforcement. Most of this patch is fixing
rustc to obey the coherence rules, which involves converting a bunch of records
to structs.

2b67d88809 Rewrite the coercion code to be more readable, more sound, and to reborrow when 
needed.

Regarding soundness: there was a subtle bug in how it was done before; see the
compile-fail test for an example.

Regarding reborrowing: reborrowing allows mut and const
slices/borrowed-pointers to be used with pure fns that expect immutable data.

2e10ea58c3 Integrate vec patterns into borrow checker. 
The tail portion of the pattern effectively borrows a vector,
but the borrow checker knew nothing about this.

c89afc3971 Fix Option camel case in a compile-fail test 
The compile fails for another reason, that triggers before the the failure for non-camel cased option, some or none undefined errors.

5b64c796a4 syntax/rustc: Improve error message for misuse of for loop 
Print out a clearer error message when a `for` gets
used with the wrong type of iterator. Also fix spans on `for` loop
bodies, and suppress some more derived errors.

Closes #3651

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.
