First step in getting LLDB ready to support multiple different type systems.

This is the work done by Ryan Brown from http://reviews.llvm.org/D8712 that makes a TypeSystem class and abstracts types to be able to use a type system.

All tests pass on MacOSX and passed on linux the last time this was submitted.
