Log:
    PR target/59575
    * config/arm/arm.c (emit_multi_reg_push): Add dwarf_regs_mask argument,
    don't record in REG_FRAME_RELATED_EXPR registers not set in that
    bitmask.
    (arm_expand_prologue): Adjust all callers.
    (arm_unwind_emit_sequence): Allow saved, but not important for unwind
    info, registers also at the lowest numbered registers side.  Use
    gcc_assert instead of abort, and SET_SRC/SET_DEST macros instead of
    XEXP.

    * gcc.target/arm/pr59575.c: New test.
