Xcode 8 requires toolchain compatibility version 2. This allows us to select the correct compatibility version based on the installed version of Xcode.
llvm-svn: 279152
Recent changes to Xcode have changed the structure of Xcode toolchains. This patch makes the xcode-toolchain goop construct a new-format Xcode toolchain that is compatible with Xcode 7.
The new format has a compatibility version key, so when a new format comes out we can support multiple formats in parallel.

This adds a new target `install-distribution-toolchain` which will install an Xcode toolchain featuring just the LLVM components specified in LLVM_DISTRIBUTION_COMPONENTS.

Summary:
Sometimes you want to install a custom compiler and use it like the system compiler without overriding the system compiler. This patch lets you create xctoolchains that the darwin command line tools can use.
To use this patch set LLVM_CREATE_XCODE_TOOLCHAIN=On in your CMake invocation and build the `install-code-toolchain` target.
After installation you can set the envar EXTERNAL_TOOLCHAINS_DIR to your installed Toolchains directory, and the TOOLCHAINS envar to the toolchain identifier (ex org.llvm.3.8.0svn). This will then cause /usr/bin/clang to call your newly installed clang.
