These mostly are checking for various reserved bits being set. The diagnostics for gpu-dependent reserved bits have a bit more context since they seem like the most likely ones to be observed in practice. This commit also improves the error handling mechanism for MCDisassembler::onSymbolStart(). Previously it had a comment stream parameter that was just being ignored by llvm-objdump, now it returns errors using Expected<T>.
