This reverts the problematic parts of
fcbebc51c7 which had caused a lot of
unintended fallout, while preserving the actual feature supported by
the patch.
Before that patch (fcbeb), and after this one, we don't emit members
of specialized bound generic types, because these can be reconstructed
by substituting the "template parameters" in the unspecialized
type. This patch carves out an exception for inline arrays, because
DWARF has special support for arrays, which allows debuggers to reason
about them without needing special support.
