Add placeholder for more extensive verification of psuedo ops This initial patch doesn't actually do much useful. It's just to show where the new code goes. Once this is in, I'll extend the verification logic to check more useful properties. For those curious, the more complicated version of this patch already found one very suspicious thing.

Fix several accidental DOS line endings in source files Summary: There are a number of files in the tree which have been accidentally checked in with DOS line endings. Convert these to native line endings. There are also a few files which have DOS line endings on purpose, and I have set the svn:eol-style property to 'CRLF' on those.
