Log Message:
-----------
[Attributor] Function signature rewrite infrastructure
As part of the Attributor manifest we want to change the signature of
functions. This patch introduces a fairly generic interface to do so.
As a first, very simple, use case, we remove unused arguments. A second
use case, pointer privatization, will be committed with this patch as
well.
A lot of the code and ideas are taken from argument promotion and we
run all argument promotion tests through this framework as well.
