DWARF5: Don't generate DW_AT_loclists_base for split compile unit DIEs.

The loclists_base attribute is used to point to the beginning of the
loclists index of a DWARF5 loclists table when using DW_FORM_loclistsx.
For split compile units the base is not given by the attribute, but is
either the first (and only) index in the .debug_loclists.dwo section,
or (when placed in a .dwp file) given by the DW_SECT_LOCLISTS row in
the .debug_cu_index section.

The loclists_base attribute is only valid for the full (or skeleton)
compile unit DIE in the main (relocatable) object. But GCC only ever
generates a loclists table index for the .debug_loclists section put
into the split DWARF .dwo file.

For split compile unit DIEs it is confusing (and not according to spec)
to also have a DW_AT_loclists_base attribute (which might be wrong,
since its relocatable offset won't actually be relocated).

gcc/ChangeLog

	DW_AT_loclists_base.
