  1. 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.

  2. Replace NormalizeArrayLen with GVN 

    GVN is actually on in release, and covers all the same things (or more), with `LowerSliceLen` changed to produce `PtrMetadata`.
