Documentation for REPL states that the default value of `useGlobal` is
`false`. It makes no distinction between a REPL that is created
programmatically, and the one a user is dropped into on the command line
by executing `node` with no arguments. This change ensures that the CLI
REPL uses a default value of `false`.

Save the setImmediate() callback arguments into an array instead of a
closure, and invoke the callback on the arguments from an optimizable
function.
60% faster setImmediate with 0 args (15% if self-recursive)
4x faster setImmediate with 1-3 args, 2x with > 3
seems to be faster with less memory pressure when memory is tight
Changes:
- use L.create() to build faster lists
- use runCallback() from within tryOnImmediate()
- save the arguments and do not build closures for the callbacks

Don't cache the exported values of fully uninitialized builtins.
This works by adding an additional `loading` flag that is only
active during initial loading of an internal module and checking
that either the module is fully loaded or is in that state before
using its cached value.
This has the effect that builtins modules which could not be loaded
(e.g. because compilation failed due to missing stack space) can be
loaded at a later point.

Until now, the docs stated that `process.noDeprecation` could be set
at runtime, but before any modules were loaded. That was not true,
because `lib/internal/util.js` was loaded during the process startup

Minimal test case:
process.noDeprecation = true;
process.EventEmitter;
This patch moves checking `process.noDeprecation` to the place where
it was actually used.

In several places throughout the code we write directly to stderr
to report warnings (deprecation, possible eventemitter memory leak).
The current design of simply dumping the text to stderr is less
than ideal. This PR introduces a new "process warnings" mechanism
that emits 'warning' events on the global process object. These are
invoked with a `warning` argument whose value is an Error object.
By default, these warnings will be printed to stderr. This can be
suppressed using the `--no-warnings` and `--no-deprecation` command
line flags. For warnings, the 'warning' event will still be emitted
by the process, allowing applications to handle the warnings in custom
ways. The existing `--no-deprecation` flag will continue to supress
all deprecation output generated by the core lib.
The `--trace-warnings` command line flag will tell Node.js to print
the full stack trace of warnings as part of the default handling.
The existing `--no-deprecation`, `--throw-deprecation` and
`--trace-deprecation` flags continue to work as they currently do,
but the exact output of the warning message is modified to occur
on process.nextTick().
The stack trace for the warnings and deprecations preserve and point
to the correct call site.
A new `process.emitWarning()` API is provided to permit userland
to emit warnings and deprecations using the same consistent
mechanism.
Test cases and documentation are included.
