Change Android build configurations (step 1).     Before this change we build Release builds size-optimized code with DCHECK, while we almost never use the Debug build which is not size-optimized.      Now change Debug build to build size-optimized code with DCHECK but still temporarily keep Release build and default configuration unchanged before everyone (the bots, scripts and developers) knows how to deal with this change.      Next steps will be:      Step 2: update developer scripts and buildbot scripts to handle the new configuration.      Step 3: change Release configuration to no DCHECK and change default configuration to Debug.      After all steps finish, this new configuration will better match Chromium and WebKit (e.g. better matches the DEBUG and RELEASE tags in WebKit layout test expectations), and makes it easier to build a performance build.
