This CL adds rounding modes for riscv64 floating point conversion instructions by suffix with 5 modes: RNE, RTZ, RDN, RUP and RMM. For example, for round to nearest (RNE), we can use `FCVTLD.RNE` According to RISCV manual 8.7 and 9.5, we changed these conversion instructions: FCVTWS FCVTLS FCVTWUS FCVTLUS FCVTWD FCVTLD FCVTWUD FCVTLUD Note: Round towards zero (RTZ) by default for all these instructions above.
