  -----------
  Allow DIBasicType (and others) to have a scope and location (#190217)

DIBasicType derives from DIType and so it already has slots to store the
scope and location of the type. However, the DIBasicType constructor
(and corresponding DIBuilder method) does not expose this, presumably
because it is not needed by C or C++.

In Ada it is more common to create one's own basic type. So, for Ada
exposing this functionality would be handy.

This patch adds a new overload of DIBuilder::createBasicType to allow
this. Because only Ada uses fixed point types, the patch simply updates
these DIBuilder methods unconditionally.

Note that DwarfUnit already handles this scenario and so no changes were
needed there.
