Ana Pazos 6ff95d95e7 [RISCV][MC] Reject bare symbols for the simm6 and simm6nonzero operand types
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.
