Subject: Add overload of DIBuilder::createArrayType (#125229)

DICompositeType has an attribute representing the name of a type, but
currently it isn't possible to set this for array types via the
DIBuilder method. This patch adds a new overload of
DIBuilder::createArrayType that allows "full" construction of an array
type. This is useful for Ada, where arrays are a bit more first-class
than C.
