  [ssci] Added Shipped field to READMEs
  
  This CL adds the Shipped field (and may update the
  License File field) in Chromium READMEs. Changes were
  automatically created, so if you disagree with any of
  them (e.g. a package is used only for testing purposes
  and is not shipped), comment the suggested change and
  why.
  
  See the LSC doc at go/lsc-chrome-metadata.

• Name: Desugar, transforming Java 8 bytecode to be Java 7 compatible
  Short Name: desugar
  URL: https://github.com/bazelbuild/bazel
  Version: 1.1.0
  License: Apache 2.0
  Security Critical: no
  Shipped: yes
  
  Description:
  Desugar is a Google-developed open-source Java library used by the build process
  to transform Java 8 bytecode to Java 7. It is used to enable Java 8 features
  such as lambda experssions for Chrome on Android.
  
  Googlers: See: go/desugar
  
  Local Modifications:
  * Added BUILD.gn, proguard.flags.
  * Made all lambdas be "stateful" to avoid <clinit> bloat.
  * Desugar_deploy.jar split into Desugar.jar and Desugar_runtime.jar.
  * Desugar.jar has been run through r8.jar to remove unused .class files.
  
  Update instructions (requires @google.com account for uploading):
  * Check out Bazel from https://github.com/bazelbuild/bazel
  * Compile or install Bazel by following instructions on
      https://docs.bazel.build/versions/master/install.html
  * Apply stateful-lambdas.patch:
      git apply $CHROMIUM_SRC/third_party/bazel/desugar/stateful-lambdas.patch
  * Build Desugar_deploy.jar:
      bazel build //src/tools/android/java/com/google/devtools/build/android/desugar:Desugar_deploy.jar
  * Move Desugar_deploy.jar to location within Chromium:
      rm $CHROMIUM_SRC/third_party/bazel/desugar/Desugar.jar
      mv bazel-bin/src/tools/android/java/com/google/devtools/build/android/desugar/Desugar_deploy.jar $CHROMIUM_SRC/third_party/bazel/desugar/Desugar.jar
  * Update Desugar_runtime.jar:
      unzip Desugar.jar "com/google/devtools/build/android/desugar/runtime*"
      zip -rD0 Desugar_runtime.jar com
      rm -r com
  * Shrink via r8 (optional - reduces size by about 66%).
      java -jar ../../r8/lib/r8.jar --debug --classfile --output Desugar.new.jar --pg-conf proguard.flags --no-desugaring --lib ../../jdk/extras/java_8/jre/lib/rt.jar Desugar.jar
      mv Desugar.new.jar Desugar.jar
  * Perform a sanity check of chrome_public_apk:
      ninja chrome_public_apk
      bin/chrome_public_apk run
  * Update this README.chromium (Version)
  * Upload new jar to CIPD:
      cd third_party/bazel
      cipd create --pkg-def cipd.yaml
  * Update revision //DEPS
