Added libdisasm to the repository. This library is no longer under development so there

is no reason not to keep it locally. Implemented a basic disassembler which can be used
to scan bytecode for interesting conditions. This should be pretty easy to add to for
things other than exploitability if there is a desire. This also adds several tests to
the windows exploitability ranking code to take advantage of the disassembler for x86
code.

BUG=None
TEST=DisassemblerX86Test.*
