This makes riscv compile with the version of clang(++) I have on my
workstation.

This patch fixes a potential crash if an unnamed CSR is accessed and
debug flags are enabled that print disassembly. Unknown CSRs will be
identified as "??" followed by the address that was used.

This patch moves static portions of the compressed instruction
definitions out of the ISA generated code.

Some of the files in earlier patches rearranging instruction definitions
were missing copyright and license information. This patch adds them.

This patch removes the static parts of the RISC-V atomic memory
instructions out of the ISA generated code and into arch/riscv/insts. It
also makes the LR and SC instructions subclasses of MemInst from
arch/riscv/insts/mem.hh.

This patch moves static portions of the memory instructions out of the
ISA generated code and puts them into arch/riscv/insts. It also
simplifies the definitions of load and store instructions by giving
them a common base class.

This patch removes the Unknown instruction type out of the ISA generated
code and puts it into arch/riscv/insts. Since there isn't any dynamic
behavior to it, all that's left behind is a template for creating a new
Unknown instruction.

This patch removes static portions of the standard instruction types
from the generated ISA code and puts them into arch/riscv/insts. Some
dynamically-generated content is left behind for each individual
instruction's implementation. Also, BranchOp is removed due to its
similarity with ImmOp and ImmOp and UImmOp are joined into a single
templated class, ImmOp<T>.

This patch creates an "insts" directory in src/arch/riscv to store
static portions of instruction definitions that aren't part of the code
generated by the ISA description. It serves as a starting point for
future patches to simplify the ISA description.
