auto merge of #13208 : Tohie/rust/master, r=alexcrichton
Check that the old value was 1 and not 0 when dropping a Arc value.
Closed #13210.
Support new attribute syntax in vim syntax file
configure: Accept LLVM 3.4.X during configuration

The previous regex was a bit to strict, rejecting versions such as 3.4.1 which
is apparently the version which travis is currently installing, causing all
travis builds to fail.
auto merge of #13215 : sfackler/rust/vim-attr, r=alexcrichton
auto merge of #13211 : csherratt/rust/arc_fix, r=alexcrichton

This is a fix for #13210. fetch_sub returns the old value of the atomic variable, not the new one.

The previous regex was a bit to strict, rejecting versions such as 3.4.1 which

mk: Fix 'make dist' on Mac
auto merge of #13218 : brson/rust/dist-mac, r=sfackler
mk: Don't touch config.tmp or tmp/dist as root. Closes #13190

When running `make install` we are touching these files that can't
then be removed later.

Rename `from_iterator` to `from_iter` for consistency.

Correct printing (sort, new lines), reading on stdin.

rustc: fixed regionck for owned trait casts.

Regionck didn't do any checks for casts/coercions to an owned trait,
which resulted in lifetimes of the source pointer
to be ignored in the result of such cast.

This fix constraints all regions of the source type of the cast/coercion to be superregions
of each region of the target type (if target trait definition has some lifetime params),
or of 'static lifetime (if there're no lifetime params in target trait's definition).

Closes #5723
Closes #9745
Closes #11971
