e9492cca - [TableGen] DecoderEmitter clean-ups and modernization. (#84832)

[TableGen] DecoderEmitter clean-ups and modernization. (#84832) The decoder emitter is showing some signs of age. This patch makes a few kinds of clean-ups: - Use ranged-for more widely, including using enumerate() for those loops maintaining a loop index along with the items. - Reduce the number of arguments to fieldFromInsn (removes an out reference parameter: CodingStandards). The insn_t argument to insnWithID can/should probably be removed soon too since modern C++ allows us to return a local container without a copy. - Use raw strings for the large emitted code segments. This enhances both readability and modifiability.
