[cfe-commits] [PATCH] Simplify StringSwitch

[Gabor Greif]

Hi all,

attached patch simplifies StringSwitch and gets rid of the
Copy{Constructible|Assignable} constraint on the type parameter.

It should also be a bit more efficient, in runtime and space.

I know that several PRs are open against LLVM optimizations
that focus on this construct, so I did not commit this directly.

Ok to commit (someday) ?

Cheers,

	Gabor
