47ea57fead rustc: Add suffix ".rc" to LLVM module identifier 
LLVM code generator emits the ".file filename" directive for ELF
backends. Value of the "filename" is set as the LLVM module identifier.
Due to a LLVM MC bug[1], LLVM crashes if the module identifer is same as
other symbols such as a function name in the module.

This patch adds a ".rc" suffix (means crates) to LLVM module identifier
to workaround the bug.

Fixes issue #1251.

1c9f97b669 stdlib: added (2,3,4)-valued logic ADTs 
This is useful for writing caches and perhaps in typestate predicates.
It also adds a companion module for bool with from_str, to_str, ... fns.

a6b2a2cdb1 Separate vec::map and vec::map_mut 
The safe-reference checker requires a copy of each mapped-over element
only when the vector is mutable. Let's not pay that cost for immutable

f6491bb426 Update stdlib, compiler, and tests to new kind system 
This involved adding 'copy' to more generics than I hoped, but an
experiment with making it implicit showed that that way lies madness --
unless enforced, you will not remember to mark functions that don't
copy as not requiring copyable kind.

cefff237bf Make tag, resource and object constructors take their arguments by copy 
Doing something like some([1, 2, 3]) will now no longer create a temporary
copy of the vector. It will also be easier for the kind checker to see that
putting a resource into a data-structure constructor is safe.

4e03112141 Add a pass-by-copy parameter passing convention 
This is intended to solve the problem of how to pass arguments to
constructor functions -- you want to move in rvalues, but not have to
explicitly copy stuff that is not an rvalue. The by-copy passing
convention will ensure the callee gets its own copy of the value. For
rvalues, it'll just pass off the value. For lvalues, it'll make a
copy.
