[Darwin, PPC, Mode Iterators 2/n] Eliminate picbase expanders.
We can use the mode iterators directly with an @pattern to avoid the need for an expander that was only there to pass the mode through. gcc/ChangeLog: 2019-09-26 Iain Sandoe <iain@sandoe.co.uk> * config/rs6000/darwin.md: Replace the expanders for load_macho_picbase and reload_macho_picbase with use of '@' in their respective define_insns. (nonlocal_goto_receiver): Pass Pmode to gen_reload_macho_picbase. * config/rs6000/rs6000-logue.c (rs6000_emit_prologue): Pass Pmode to gen_load_macho_picbase. * config/rs6000/rs6000.md: Likewise.
