Add back missing use of profdata for new builds.

I didn't realize that this was also using an `rstrip()` pattern with the
numbering scheme that breaks use of profdata files. Switching to the new
method restores our optimized binaries.

Android Clang/LLVM Toolchain

For the latest version of this doc, please make sure to visit: Android Clang/LLVM Toolchain Readme Doc

You can also visit the Android Clang/LLVM Prebuilts Readme Doc for more information about our prebuilt toolchains (and what versions they are based upon).

Build Instructions

$ mkdir llvm-toolchain && cd llvm-toolchain
$ repo init -u https://android.googlesource.com/platform/manifest -b llvm-toolchain
$ repo sync -c
$ python toolchain/llvm_android/build.py

If building on Linux, pass --no-build windows to build.py to skip building Clang for Windows.

If you have an additional llvm tree built and present in your $PATH, then build.py might fail during the Windows build of libcxxabi with the error 'libstdc++ version must be at least 4.8.'. The solution is to remove that path from your $PATH before invoking build.py.
