Creates a pass called eliminate dead functions that looks for functions that could never be called, and deletes them from the module. To support this change a new function was added to the Pass class to traverse the call trees from diffent starting points. Includes a test to ensure that annotations are removed when deleting a dead function. They were not, so fixed that up as well. Did some cleanup of the assembly for the test in pass_test.cpp. Trying to make them smaller and easier to read.
