[PATCH] D22590: Ignore virtual registers when computing debug information

[Derek Schuff via llvm-commits]

I think this surely isn't the final solution for debug info on virtual targets like wasm (that will probably require some more design work in the medium term), but not crashing is certainly a good start.
So, I think this code is fine. But the first part of the commit description isn't quite right, because it doesn't actually ignore virtual registers; it does track the clobbers (it just knows they don't have aliases and doesn't try to put them into the set of changing registers).
