Please take a look.

Description:
Patch at http://codereview.appspot.com/download/issue140041_1.diff

Automatically do the equivalent of freeMachineCodeForFunction(F) when F
is being destroyed. This allows users to run global optimizations like
globaldce even after some functions have been jitted.

This patch also removes the Function* parameter to
JITEventListener::NotifyFreeingMachineCode() since it can cause that to
be called when the Function is partially destroyed. This change will be
even more helpful later when I think we'll want to allow machine code to
actually outlive its Function.

This patch depends slightly on the test in
http://codereview.appspot.com/133043, but I can make them independent if
this gets reviewed first.
