re PR rtl-optimization/44169 (Wrong code while generating TLS offsets)
PR target/44169
* config/rs6000/rs6000.md (load_toc_v4_PIC_1b): Add label operand.
* config/rs6000/rs6000.c (rs6000_legitimize_tls_address): Pass label
rtx to gen_load_toc_v4_PIC_1b. Tidy.
(rs6000_emit_load_toc_table): Likewise.
