Currently, lib/_tls_legacy.js and lib/crypto.js cannot be loaded when --use-strict is passed to node. In addition to that, console.trace throws because it uses arguments.callee. This change fixes these issues and adds a test that makes sure every external built-in module can be loaded with require when --use-strict is enabled. Please note that this change does not fix all issues with built-in modules' code running with --use-strict. It is very likely that some code in the built-in modules still fails when passing this flag. However, fixing all code would require us to enable strict mode by default in all builtins modules, which would certainly break existing applications. Fixes #9187.
