That is, if you have an enum type that is subject to the nullable
pointer optimization, but the null variant has a nonzero number of
fields, and you declare a static whose value is of that variant, then
that used to be an ICE but this change fixes it.
`doc/po/*.pot` files are generated automatically using `po4a` and they includes timestamps in their content. The files can cause huge conflicts unnecessarily. Also, removing them save disk space if you are not a translator.

This is something I have been meaning to do for awhile, but upon inspection of the `eof` method on all of the `Reader` impls you may find some interesting surprises. The method returns a good answer for almost all wrapped I/O objects (buffered readers, mem readers, util readers, etc), but the actual return value on all I/O objects themselves is almost always useless.
Almost no I/O object other than a file actually knows when it's hit EOF or not. I think that pretending that all objects know when they've hit the end when almost none do is probably a bad idea. I can't really come up with a good answer to "is this file descriptor at eof" or "is this tcp stream at eof" much less "is this udp socket at eof". Due to being unable to answer these questions for *all* readers, I believe that it shouldn't be a part of the core `Reader` trait.
The methods contained in `std::num::{Algebraic, Trigonometric, Exponential, Hyperbolic}` have now been moved into `std::num::Real`. This is part of an ongoing effort to simplify `std::num` (see issue #10387).
`std::num::RealExt` has also been removed from the prelude because it is not a commonly used trait.

This trait seems to stray too far from the mandate of a standard library as implementations may vary between use cases. Third party libraries should implement their own if they need something like it.
This closes#5316.

This is just an unnecessary trait that no one's ever going to parameterize over
and it's more useful to just define the methods directly on the types
themselves. The implementors of this type almost always don't want
inner_mut_ref() but they're forced to define it as well.
So, like I mentioned in issue #10955 it doesn't seem like we need to call ```ty::subst_tps``` when the method is generic. But then I realized that this function doesn't mutate any of its input, and the return value is unused. Plus the type param substitution seems to be taken care of in ```trans_fn_ref_with_vtables```, so I thought I'd just try to remove it. As far as I can tell everything works.
This closes#10955.

`expand_include_str()` in libsyntax seems to have corrupted the CodeMap by always setting the BytePos of any included files to zero. It now uses `CodeMap::new_filemap()` which should set everything properly. This should fix issue #11322 but I don't want to close it before I have confirmation from the reporters that the problem is indeed fixed.
If we bootstrap a cross compile from a stage1 compiler, then the stage1 compiler
already knows about the rustc => rustlib change, so we need to not add the extra
flag if it's a stage0 version of a target from a stage1 of another target.

A typed arena is a type of arena that can only allocate objects of one
type. It is 3x faster than the existing arena and 13x faster than malloc
on Mac.

If a reexport comes from a non-public module, then the documentation for the
reexport will be inlined into the module that exports it, but if the reexport is
targeted at a public type (like the prelude), then it is not inlined but rather
hyperlinked.
