RISC-V: Fix minor issues with FP csr instructions.
Mel Chen <mel.chen@sifive.com> gas/ * testsuite/gas/riscv/alias-csr.s: Add testcase for CSR-access alias instructions. * testsuite/gas/riscv/no-aliases-csr.d: Run testcase alias-csr.s with -Mno-aliases. * testsuite/gas/riscv/alias-csr.d: Run testcase alias-csr.s. * testsuite/gas/riscv/priv-reg.d: Update. opcodes/ * riscv-opc.c (riscv_opcodes): Set frsr, fssr, frcsr, fscsr, frrm, fsrm, fsrmi, frflags, fsflags, fsflagsi to alias instructions. * riscv-opc.c (riscv_opcodes): Adjust order of frsr, frcsr, fssr, fscsr.
