Add LLVM binaries for iOS 9 device

Look for locally built/binary dropped LLVM headers and libraries when building for iOS device
in WebKitBuild/usr/local.
Currently Mac and iOS look for the locally built/binary dropped LLVM in different directories:
WebKitBuild/usr/local and /usr/local/LLVMForJavaScriptCore, respectively. This difference is
due to dependencies with the Apple internal build system. We should look to resolve the
Apple internal dependencies and standardize on one location for both platforms.

Implement support for building LLVM for ARM64-based iOS devices.
* Scripts/build-jsc: Enable the FTL when building for Mac or iOS device.
* Scripts/copy-webkitlibraries-to-product-directory: Move logic to clean
an existing build earlier in the file such that remove previously built
libraries before building/copying new ones (if applicable).
(fileContains): Moved function outside of if-block.
(isContentOfFileEqualToString): Renamed; formerly named fileContentsEquals().
(buildLLVM): Added. Extracted machinery to build LLVM into this function and
added logic to build LLVM for ARM64-based iOS devices.
(symlinkLLVMLibrariesIfNeeded): Added. Extracted machinery to symlink the built
LLVM into the WebKitBuild directory.

Add LLVM 3.6.2 binaries for ARM64-based iOS devices. We make use of LLVM for the FTL,
which is enabled for 64-bit iOS devices.
I built these binaries by performing the following:
1) Check out WebKit to a directory like /some/path/OpenSource.
2) Download and expand the archive <http://llvm.org/releases/3.6.2/llvm-3.6.2.src.tar.xz> into /some/path/OpenSource/llvm.
3) In /some/path/OpenSource, delete the WebKitBuild directory to ensure a clean build.
4) Run `Tools/Scripts/build-jsc --release --device ARCHS=arm64 ONLY_ACTIVE_ARCH=NO` to build both LLVM and JavaScriptCore.
5) Run `Tools/Scripts/export-llvm-build -i WebKitLibraries/LLVMIncludesIOSDevice9.tar.bz2 -l WebKitLibraries/LLVMLibrariesIOSDevice9.tar.bz2 -b llvm/wkLLVMBuild -B llvm/wkLLVMBuild/Release+Asserts -s llvm` to produce files LLVM{Includes, Libraries}IOS9.tar.bz2.
* LLVMIncludesIOS9.tar.bz2: Added.
* LLVMLibrariesIOS9.tar.bz2: Added.
