arm64: insn: remove BUG_ON from codegen
During code generation, we used to BUG_ON unknown/unsupported encoding or invalid parameters. Instead, now we report these as errors and simply return the instruction AARCH64_BREAK_FAULT. Users of these codegen helpers should check for and handle this failure condition as appropriate. Otherwise, unhandled codegen failure will result in trapping at run-time due to AARCH64_BREAK_FAULT, which is arguably better than a BUG_ON.
