[Debug Info] add a template class DITypedArray.

Browse Source 
Typedef DIArray to DITypedArray<DIDescriptor>. Also typedef DITypeArray as
DITypedArray<DITypeRef>.

This is the third of a series of patches to handle type uniqueing of the
type array for a subroutine type.

This commit should have no functionality change.
