Before the conversion to LLVM-IR dialect and ultimately LLVM IR, FIR is partially rewritten into a codegen form. This patch adds that pass, the fircg dialect, and the small set of Ops in the fircg (sub) dialect. Fircg is not part of the FIR dialect and should never be used outside of the (closed) conversion to LLVM IR. Authors: Eric Schweitz, Jean Perier, Rajan Walia, et.al.
