This adds support for expressions like

    Switch(arg)
      .Case(1, result1)
      .CASES((2, 3), result2)
      .Default(result3)

Currently these expressions are compiled simply as short-hand for

    If(arg == 1, result1)
      .ElseIf(arg == 2 || arg == 3, result2)
      .Else(result3)

but in the future we should be able to optimize it better.

The CASES macro ugliness is unfortunately necessary until we're
allowed to use C++11.  Later we'll be able to change it to
real C++ code like "Cases({2, 3}, result2)" (which clang-format
will then format a bit more nicely too).

This was introduced in be9da705 by

It appears that RenderWidgetHostViewMac::Destroy is never getting
called in some instances, and that is resulting in crashes when we end
up in its destructor, which is called by Objective C's runtime.

I suspect that this is a leak somewhere, and that on other platforms we
simply never call the destructor.

Call the necessary bits of RenderWidgetHostViewMac::Destroy to avoid
crash when a RenderWidgetHostImpl reaches its destructor before its
view_ has been reset.

Also, turn the weak pointers to RenderWidgetHostViewBase in
RenderWidgetHostImpl and RenderWidgetHostViewGuest
to use base::WeakPtr to prevent the many dangling instances.

In the interest of phasing out the totally unnecessary
*Chrome*ExtensionFunction base classes, this establishes a
ChromeExtensionFunctionDetails object which can be created
by extension function implementations in //chrome who need
access to Chrome-specific details.

This object can be very easily composed into such function
implementations such that they can move away from using
e.g. ChromeAsyncExtensionFunction or
ChromeUIThreadExtensionFunction as a base class and instead
rely on more universal and generic ExtensionFunction and its
immediate derivatives.

A conversion of the tabs API ExecuteCodeInTabFunction is
included for demonstration purposes.
