bfd signed overflow fixes
Aimed at quietening ubsan. include/ * opcode/mmix.h (PUSHGO_INSN_BYTE): Make unsigned. (GO_INSN_BYTE, SETL_INSN_BYTE, INCML_INSN_BYTE, INCMH_INSN_BYTE), (INCH_INSN_BYTE, SWYM_INSN_BYTE, JMP_INSN_BYTE): Likewise. bfd/ * elf32-rx.c (elf32_rx_relax_section): Avoid signed overflow. * libaout.h (N_SET_INFO, N_SET_FLAGS): Likewise. * netbsd.h (write_object_contents): Likewise. * elf32-arm.c (bfd_elf32_arm_vfp11_erratum_scan): Likewise. * libhppa.h (HPPA_R_CONSTANT): Don't signed extend with shifts. (stm32l4xx_create_replacing_stub_vldm): Don't truncate high bits with shifts. * elf32-nds32.h (R_NDS32_RELAX_ENTRY_DISABLE_RELAX_FLAG): Define using 1u shifted left. Ditto for other macros. * mmo.c (LOP): Make unsigned.
