mk: Replace 'compile_and_link' with 'oxidize'
Fixed a typo in list's find() documentation.
Make `if` and `while` conditions temporary

Closes #12033
Fix the signature of CreateSymbolicLinkW

Closes #12123
auto merge of #12126 : brson/rust/oxidize_mk, r=alexcrichton

I've always thought 'compile_and_link: ...' looked really awkward in our build output. Replace it with something more interesting. I'm open to alternatives to 'oxidize', like 'compile', anything but 'compile_and_link'.
std: Stop parameterizing some memcpy functions over RawPtr

It unsafe assumptions that any impl of RawPtr is for actual pointers,
that they can be copied by memcpy. Removing it is easy, so I don't
think it's solving a real problem.
std: Clean up the swap function a little
Rearranged enum section of tutorial for clarity.

This version starts with the simple case and builds on it.

This version starts with the simplest case and builds on it. I believe it flows better.

Replace ```v``` with ```ls```.

IR Before:

```llvm
normal-return:                                    ; preds = %while_body
  %113 = load i64* %i
  %114 = sub i64 %113, 1
  store i64 %114, i64* %i
  br label %while_cond
```

IR After:

```llvm
normal-return:                                    ; preds = %while_cond
  store i8 %11, i8* %0
  %18 = load i8* %0, !range !0

Closes #12123
auto merge of #12143 : brson/rust/swap, r=alexcrichton

Thinking about swap as an example of unsafe programming. This cleans it up a bit. It also removes type parametrization over `RawPtr` from the memcpy functions to make this compile.
Consolidate codegen-related compiler flags

Move them all behind a new -C switch. This migrates some -Z flags and some
top-level flags behind this -C codegen option.

The -C flag takes values of the form "-C name=value" where the "=value" is
optional for some flags.

Flags affected:

* --llvm-args           => -C llvm-args
* --passes              => -C passes
* --ar                  => -C ar
* --linker              => -C linker
* --link-args           => -C link-args
* --target-cpu          => -C target-cpu
* --target-feature      => -C target-fature
* --android-cross-path  => -C android-cross-path
* --save-temps          => -C save-temps
* --no-rpath            => -C no-rpath
* -Z no-prepopulate     => -C no-prepopulate-passes
* -Z no-vectorize-loops => -C no-vectorize-loops
* -Z no-vectorize-slp   => -C no-vectorize-slp
* -Z soft-float         => -C soft-float
* -Z gen-crate-map      => -C gen-crate-map
* -Z prefer-dynamic     => -C prefer-dynamic
* -Z no-integrated-as   => -C no-integrated-as

As a bonus, this also promotes the -Z extra-debug-info flag to a first class -g
or --debuginfo flag.

* -Z debug-info         => removed
* -Z extra-debug-info   => -g or --debuginfo

IterBytes for IpAddr and SocketAddr
Update comment in contravariant test

The previous definition was actually describing covariance.
Fixing to describe contravariance while keeping 'static in the definition was tricky so just changed to use 'short and 'long.
Implement List's any() function

This is needed for cases where we only need to know if a list item
matches the given predicate (eg. in Servo, we need to know if attributes
from different DOM elements are equal).
auto merge of #12149 : thomaslee/rust/ipaddr_deriving_iter_bytes, r=cmr

This is a fairly trivial (but IMHO handy) change to implement IterBytes for IpAddr and SocketAddr.

I originally stumbled across this because I wanted to use a SocketAddr as a HashMap key and discovered that I couldn't do it directly. Had to impl IterBytes on a new intermediate type to work around it.
