Bug 1289847 - part 2 - work around Mac linking failures when Rust is enabled; r=mshal Current stable versions of Rust use two Rust-specific personality routines to perform exception handling, which empirically does not play well with the Mac linker's optimizations for using compact unwind formats. Nightly Rust has solved this issue, but for now, we'll have to use -no_compact_unwind to disable the linker optimization. The size impact is negligible (0.02%) and will be going away once nightly Rust becomes stable.

Bug 1289847 - part 1 - use a newer ld for Mac builds; r=mshal The ld that we use for Mac builds is old (Xcode circa OS X 10.7), and also crashes in various ways when we try to use newer Rust versions and/or pass options to make the linker work with newer Rust versions. To mitigate this, let's build with a newer linker, compiled from: https://github.com/tpoechtrager/cctools-port We use this port, rather than the packages from opensource.apple.com, because the packages from Apple have decidely non-intuitive build systems, and require some hacking to get to build. This port, in contrast, is simply built with: CFLAGS='-mcpu=generic -mtune=generic' ./configure --target=x86_64-apple-darwin11 env MACOSX_DEPLOYMENT_TARGET=10.7 make and the resulting x86_64-apple-darwin11-ld is renamed as 'ld' and packaged up for automation's purposes. However, since this linker is newer, it also produces bits of Mach-O that our older build tools don't understand. Fortunately, we can pass appropriate options to the linker to turn off generation of those Mach-O bits.

Bug 1290156 - Remove the DEBUG-only lockOwner member from vixl::Simulator; r=terrence The checks that the `lockOwner` member was used for are redundant now that `js::Mutex` uses `PTHREAD_MUTEX_ERRORCHECK` in `DEBUG` builds.

Bug 1290156 - Remove the DEBUG-only lockOwner member from GlobalHelperThreadState; r=terrence The checks that the `lockOwner` member was used for are now redundant given that `js::Mutex` uses `PTHREAD_MUTEX_ERRORCHECK` in `DEBUG` builds. In methods where we asserted `isLocked()`, we now pass in an `AutoLockHelperThreadState` reference for compile-time proof of lock holding. This is mostly a mechanical change.
