Ok, `__traits(isSame)` always returns false for values.

This is very unfortunate as `std.traits.isSame` is one of the most used template instances in typical std.meta-programming and has a noticeable impact on time and space complexity now that AliasAssign-enabled versions of std.meta members have removed the need for other costly recursive template patterns.

I suggest we add a new builtin trait that exactly mimics std.traits.isSame or inline the calls to `isSame` in `std.traits.meta`. This is gonna significantly speed up functions in std.meta, for instance `staticIndexOf`, `EraseAll`, `GenericReplace`, `ReplaceAll`, `Pack`.
