The test expects a specific precision value that is not met on all V8 versions anymore due to a recent consolidation of different algorithms across the V8 code base.
This makes sure the preceision is tested against one digit less to keep the test working on all V8 versions.

In Node.js 12, the formatting of console arguments will change slightly.
Previously, a string other than the first argument was formatted using
single quotes if the first argument was non-string. Now, quotes are
never added regardless of position of a string argument.
To make test compatible in all Node.js versions, I work around by
ensuring the first argument to console.log is a string which prevents
the quotes from being added on older versions of Node.js.

- inline single-use function declarations as expressions when permissible
- depend on `reduce_vars`
- enabled by default
- disable for speed critical code
fixes#2464
- empty body
- single `AST_Return`
- single `AST_SimpleStatement`
- avoid `/*#__PURE__*/`
Miscellaneous
- enhance single-use function substitution
fixes#281
- all arguments may accept constant values
- return constant value
- free of side effects
- available & identical across locales and runtime environments
- move these optimisations out from `Compressor` to `OutputStream`
- fixes behaviour inconsistency when running uglified code from global or module levels due to redefinition
That particular version of Node.js has messed up error messages, so provide a version-specific workaround.
Also fixed an formatting issue which would cause `expect_stdout` to fail if error message contains excerpts of input.
Apply `expect_stdout` to more applicable tests.
Bookmarklet for instance implicitedly assumes a "completion value" without using `return`.
The `expression` option now supports such use cases.
Optimisations on IIFEs also enhanced.

- remove call to evaluate() in is_constant() and let nested optimize() does its job instead
- reject RegExp in is_constant() and remove special case logic under collapse_vars
- operands to conditionals optimisation are now always evaluate()-ed
- throw error in constant_value() instead of returning undefined to catch possible bugs, similar to make_node_from_constant()
- optimise binary boolean operators under `evaluate` instead of `conditionals`
