[DebugInfo] Fix emitting DWARF64 .debug_loclists sections (14/19). The size of the offsets in the table depends on the DWARF format. Differential Revision: https://reviews.llvm.org/D87020

DebugInfo: Fix LTO+DWARFv5 loclists The loclists_table_base was being overwritten for each CU even though only one loclists contribution is made so everything but the last CU would have a label that was never defined and fail to assemble.
