This fixes the large number of problems that prevented cross crate
methods from ever working. It also fixes a couple lingering bugs with
polymorphic default methods and cleans up some of the code paths.
Closes#4102. Closes#4103.
Currently, by-copy function arguments are always stored into a scratch
datum, which serves two purposes. First, it is required to be able to
have a temporary cleanup, in case that the call fails before the callee
actually takes ownership of the value. Second, if the argument is to be
passed by reference, the copy is required, so that the function doesn't
get a reference to the original value.
But in case that the datum does not need a drop glue call and it is
passed by value, there's no need to perform the extra copy.

Under valgrind on 64->32 cross compiles the dynamic linker is emitting
some error messages on stderr, which interferes with the tests that
are checking stderr.
Was updating some code of mine to use the new `std`/`extra` library names, and noticed a place where docs for `std::libc` hadn't been updated. Then I updated some top-level docs for the new libraries' names, too.
The code compiles and runs under windows now, but I couldn't look up any
symbol from the current executable (dlopen(NULL)), and calling looked
up external function handles doesn't seem to work correctly under windows.
This the beginning of a fix for #7095.
This commit fixes rustc's debug info generation and turns debug-info tests back on.
The old generator used to write out LLVM metadata directly, however it seems that debug metadata format is not stable and keeps changing from release to release. So I wrapped LLVM's official debug info API - the DIBuilder class, and now rustc will use that.
One bit of old functionality that still doesn't work, is debug info for function arguments. Someone more familiar with the compiler guts will need to look into that.
Also, unfortunately, debug info is still won't work on Windows,- due to a LLVM bug (http://llvm.org/bugs/show_bug.cgi?id=16249).
Resolves issues #5836, #5848, #6814
I'm pretty sure this got adequately reviewed by a combination of @nikomatsakis and @graydon so I'm rubber stamping it because I really want this in (it makes it much less likely for me to swap, allowing me to get more work done).
This change prevents the indentation in code blocks inside the /// doc comments
from being eaten. The indentation that is the same across the consecutive doc
comments is removed by the uindent_pass in librustdoc.
The bug can be seen, e.g., here: http://static.rust-lang.org/doc/std/iterator.html#example-12
I also altered how the block comments are treated, for consistency. There isn't much testing done on the documentation output (I added a few tests of my own for the modified function), so I don't know if anything relied on the previous behavior. I checked a number of documentation files and observed either no change in output or changes that consistent of the above bug being fixed.
