Create proguard-rules.pro, disabling obfuscation. The BaselineProfileGenerator needs to run on an AOSP emulator. Classes in StartupBenchmark should run on a physical device to produce reliable data. The baseline-prof.txt file should be re-generated for each release. Change-Id: Iaceb4e5c6d2f927dc545454a44dea43951dfaf6dpull/2/head
