//
// These passes are used to cleanup the output of GCC. GCC's output is
// unneccessarily gross for a couple of reasons. This pass does the following
// things to try to clean it up:
//
// * Eliminate names for GCC types that we know can't be needed by the user.
// * Eliminate names for types that are unused in the entire translation unit
// * Fix various problems that we might have in PHI nodes and casts
// * Link uses of 'void %foo(...)' to 'void %foo(sometypes)'
//
// Note: This code produces dead declarations, it is a good idea to run DCE
// after this pass.
