    RISC-V: Default-initialize variable.
    
    This patch initializes saved_vxrm_mode to VXRM_MODE_NONE.  This is a
    warning (but no error) when building the compiler so better fix it.
    
    gcc/ChangeLog:
    
            * config/riscv/riscv.cc (singleton_vxrm_need): Init
            saved_vxrm_mode.
    
    (cherry picked from commit e6fea0a8be95e2a1cbe733301a205b8c00db9202)
