RISC-V: PR28733, add missing extension info to 'unrecognized opcode' error
Currently we report errors as "unrecognized opcode `fence.i'" when the
opcode isn't part of the selected extensions.
This patch expands that error message to include the missing extension
information. For example, now the error message would be "unrecognized
opcode `fence.i', extension `zifencei' required".
If the opcode is not a part of any extension, the error message reverts
to "unrecognized opcode `<op statement>'".
