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');
^^^^
1 error(s), 0 warning(s)

Compilation FAIL.
Upgrade closure compiler to v20191027
* Add a test for built file size
Adds a script test for building Blockly's compressed files and
checking their size to prevent unexpected increases.
* Update size for new changes
* Add full stop
