Feature Implemented.

This patch adds a -post-link-opts option to llvm-ld which allows an arbitrary
program to optimize bytecode after linking. The program is passed two file
names. The first is the input (linked bytecode) the second is where it must
place its output (presumably after optimizing). If the output file is bytecode
(after the program is run), it is used as a substitute for the input for further
linking steps.  This will allow things like poolalloc to be written as a
separate program instead of a loadable module or built into LLVM.

Patch here:
