Bug 152290

* SUMMARY Builtin source should be minified. In many cases, the extracted builtin code can be minified more. Here are some existing examples: 1. Whitespace can be stripped. Primarily leading whitespace and many trailing newlines. This seems to account for sometimes 20% of the size of these builtins. 2. Lines that end up as only comments can be removed entirely. For example: > const JSC::ConstructAbility s_moduleLoaderObjectNewRegistryEntryCodeConstructAbility = JSC::ConstructAbility::CannotConstruct; > const int s_moduleLoaderObjectNewRegistryEntryCodeLength = 713; > const char* s_moduleLoaderObjectNewRegistryEntryCode = > "(function (key)\n" \ > "{\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > " //\n" \ > "\n" \ > " \"use strict\";\n" \ > "\n" \ > " return {\n" \ > " key: key,\n" \ > " state: this.Fetch,\n" \ > " metadata: undefined,\n" \ > " fetch: undefined,\n" \ > " translate: undefined,\n" \ > " instantiate: undefined,\n" \ > " resolveDependencies: undefined,\n" \ > " dependencies: [], //\n" \ > " dependenciesMap: undefined,\n" \ > " module: undefined, //\n" \ > " error: undefined,\n" \ > " };\n" \ > "})\n" \
