We used to do such things, using pointers rather than UIDs even, and I fixed a
number of such issues to avoid codegen differences.  But hey, if you could
prove that a DECL uid would never affect decisions taken by the compiler,
including decisions that might depend on the order in which you perform similar
tests over difference pieces of code, more power to you, don't let me stand on
your way.  Bonus points if you can devise a way to avoid such dependences on
UIDs from being accidentally introduced at a later time.
