As of closure-compiler-v20191027.jar the compile now breaks due to a lack of ‘goog’ being defined.
../../temp_core/constants.js:24: ERROR - [JSC_UNDEFINED_VARIABLE] variable goog is undeclared
goog.provide('Blockly.constants');

Upgrade closure compiler to v20191027
* Google changed from an Inc to an LLC.
This happened back in 2017 but we didn’t notice. Officially we should update files from Inc to LLC when they are changed as part of regular edits, but this is a nightmare to remember for the next decade.
* Remove project description/titles from licenses
This is no longer part of Google’s header requirements. Our existing descriptions were useless (“Visual Blocks Editor”) or grossly obselete (“Visual Blocks Language”).
* License no longer requires URL.
* Fix license regexps.
No Blockly instances need both Horizontal and Vertical flyouts. Dropping one of these saves 2 KB. Some don’t need flyouts at all (e.g. Blockly Games Puzzle or readonly documentation blocks).
tests/compile/compile.sh improvements
* Allow running from either Blockly root or local dir.
* Allow the use of npm google-closure-library.
* Log compiler/library versions
* Log full *compiler*.jar filename. Limit to one match.
* Add npm instructions for both compiler and library.
* Minor stylistic polish.
