Subject: Move llvm/Support/TypeBuilder.h -> llvm/TypeBuilder.h. This completes
 the move of *Builder classes into the Core library.

No uses of this builder in Clang or DragonEgg I could find.

If there is a desire to have an IR-building-support library that
contains all of these builders, that can be easily added, but currently
it seems likely that these add no real overhead to VMCore.
