9a738fd61d rt: Various tweaks to make __morestack unwinding work on linux 
When unwinding through __morestack the stack limit in the TLS is invalidated
and must be reset. Instead of actually landing at __morestack we're
just going to make all our Rust landing pads call upcall_reset_stack_limit,
which will find the stack segment that corresponds to the current stack
pointer and put the limit in the TLS.

Also massively expand the stack segment red zone to make more room for the
dynamic linker. Will fix in the future.

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.

9fb3719ded Rollback return-by-reference 
It's proving too inflexible, so I'm ripping out the extra complexity
in the hope that regions will, at some point, provide something
similar.

86c1f16a10 Fix bad interaction between last-use finding and references 
The last-use pass now takes input from the alias pass to not mark things
as last uses that are still accessed through a reference.

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.
