yes.  NopStmts do not affect any data dependences, or anything else.  

Incidentally, note that even if a NopStmt is pointed to, as the target of
a jump for instance, and we remove that NopStmt, the code remains correct,
because the PatchingChain returned by Body.getUnits() will move the jump
to point to the next statement.
