Try to fix a layering violation introduced by r213945
The dragonegg buildbot (and others?) started failing after
r213945/r213946 because `llvm-as` wasn't linking in the bitcode reader.
I think moving the verify functions to the same file as the verify pass
should fix the build. Adding a command-line option for maintaining
use-list order in assembly as a drive-by to prevent warnings about
unused static functions.
