TypeBuilder for const void*

Hi!

In Line 230 of llvm\Support\TypeBuilder.h is support for void*:

/// void* is disallowed in LLVM types, but it occurs often enough in C code that
/// we special case it.
template<> class TypeBuilder<void*, false>
   : public TypeBuilder<types::i<8>*, false> {};

If would be cool if the same thing can be added for const void*:

template<> class TypeBuilder<const void*, false>
   : public TypeBuilder<types::i<8>*, false> {};

Sure. Done in http://llvm.org/viewvc/llvm-project?view=rev&revision=95677.
Thanks!
