[PATCH] D42530: Clang permits assignment to vector/extvector elements in a const method

If you just want a better diagnostic, there's quite a bit of machinery already set up to give more specific errors about why such-and-such l-value isn't modifiable.  There may even be vector-specific diagnostics for that already, just triggered from the wrong place in the code.
