Steven Perron e43c91046b Create the dead function elimination pass
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.
