mk: target triple rename arm-unknown-android->arm-linux-androideabi
Represent enums with regular structs; no more alignment-breaking casts.
librustc: Convert all uses of old lifetime notation to new lifetime notation. rs=delifetiming
libsyntax: Stop parsing old lifetimes, except for the ones on data type declarations.
Make &self permit explicit lifetimes, but don't really use them
(this will be needed for snapshotting at some point).
librustc: Make the compiler ignore purity.

For bootstrapping purposes, this commit does not remove all uses of
the keyword "pure" -- doing so would cause the compiler to no longer
bootstrap due to some syntax extensions ("deriving" in particular).
Instead, it makes the compiler ignore "pure". Post-snapshot, we can
remove "pure" from the language.

There are quite a few (~100) borrow check errors that were essentially
all the result of mutable fields or partial borrows of `@mut`. Per
discussions with Niko I think we want to allow partial borrows of
`@mut` but detect obvious footguns. We should also improve the error
message when `@mut` is erroneously reborrowed.
Update rust.vim
