re PR target/50751 (SH Target: Displacement addressing does not work for QImode and HImode)
PR target/50751
* config/sh/sh.md (*extendqisi2_compact_reg, *extendhisi2_compact_reg):
Use arith_reg_operand predicate instead of register_operand.
* config/sh/predicates.md (movsrc_no_disp_mem_operand): Accept
only mem, simplify.
