Scott McMurray 4a7b6c0e6c More GVN for PtrMetadata 
`PtrMetadata` doesn't care about `*const`/`*mut`/`&`/`&mut`, so GVN away those casts in its argument.

This includes updating MIR to allow calling PtrMetadata on references too, not just raw pointers.  That means that `[T]::len` can be just `_0 = PtrMetadata(_1)`, for example.
