Add programs to compare R8 and ProGuard output sizes
The script r8lib_size_compare.py runs R8 and ProGuard on r8.jar to
produce a minified r8lib.jar that keeps everything marked @Keep.
By default, inlining is disabled in both R8 and ProGuard to make
method-by-method comparison much easier. Pass --inlining to enable
inlining.
By default, the script only shows methods where R8's DEX output is 5 or
more instructions larger than ProGuard+D8's output. Pass --threshold 0
to display all methods.
* Pass extra keyword arguments from build_r8lib() to toolhelper.run() to
allow disabling inlining in R8 by passing the system property
-Dcom.android.tools.r8.disableinlining=1 to the JVM.
