Summary: Fixed assertions due to invalid fixup when encoding compressed instructions (c.addi, c.addiw, c.li, c.andi) with bare symbols with/without modifiers. This matches GAS behavior as well. This bug was uncovered by a LLVM MC Disassembler Protocol Buffer Fuzzer for the RISC-V assembly language.
