Craig Topper 1edde1c1f8 Recommit "[RISCV] Relax opcode restriction for .insn."
Original commit message:
I recently added a check to make sure the lower 2 bits of the opcode
were 0x3. A post commit comment pointed out this would be allowed
for a custom extension when C is not supported.

Note, binutils does have this restriction.
