Support generating Go code (#3)
* Support generating Go code
Generate Go code for the RISC-V Go port
<https://github.com/riscv/riscv-go>.
* Clarify use of yank in Go backend
* Go: Also generate funct3, csr, and funct7 encodings
* Go: Emit all instructions
Changes to the RISC-V Go implementation obviate the need for
GO_UNUSED_INSTRUCTIONS.
* Go: Print CSRs as signed values
* Go: Update parse-opcodes to use obj.As
See https://github.com/golang/go/commit/0d9258a830c585.
* Go: Return errors out of band
* Go: Return 'ok' status instead of 'err' status
Also clean up imports.
* Go: Make gofmt-clean
* Go: Return rs2 value for each instructions
Some binary floating-point instructions (ab)use the rs2 value to hold
additional instruction data, so we need that data in the Go assembler.
