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.
After reading issue #7077, all header elements had a border. In my opinion those borders are a bit too much distraction. I tried a different approach with increasing the padding and font size, and omitting the borders.
Comparison:

Note: the highlighted code blocks are not caused by this commit.
I left the border of the code block / function signature as is. The reason behind that is that code blocks are really block elements, while headers are not. What do you guys think?
Currently, cleanup blocks are only reused when there are nested scopes, the
child scope's cleanup block will terminate with a jump to the parent
scope's cleanup block. But within a single scope, adding or revoking
any cleanup will force a fresh cleanup block. This means quadratic
growth with the number of allocations in a scope, because each
allocation needs a landing pad.
Instead of forcing a fresh cleanup block, we can keep a list chained
cleanup blocks that form a prefix of the currently required cleanups.
That way, the next cleanup block only has to handle newly added
cleanups. And by keeping the whole list instead of just the latest
block, we can also handle revocations more efficiently, by only
dropping those blocks that are no longer required, instead of all of
them.
Reduces the size of librustc by about 5% and the time required to build
it by about 10%.

Two changes:
1. Make type parameters move by default, even if they have a Copy bound. After all, they could be bound to `~T` or `~[]`. Also, this is a necessary step towards removing `copy` keyword and replacing with clone.
2. Make it illegal to move from `*T`. This is dangerous in a "moves-by-default" scenario, because it's very easy to move when working with a `*T` pointer. Also, it requires zeroing memory, which we hope to do away with someday.
