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.
