/**
* Flags are bitpacked, refer to the `RAB_INSTR_FLAGS_` macros to access them.
*
* Bit usage:
* - Bits 0 ~ 1: `r5900DisasmAsData`. Value of the `RabTrinaryValue` enum.
* - `RAB_TRINARY_VAL_TRUE` forces the instruction to be disassembled as data.
* - `RAB_TRINARY_VAL_FALSE` bypasses the global checks for disassembling a word as data. A word will still be disassembled as data if it can't be decoded.
* - `RAB_TRINARY_VAL_NONE` leaves this decision to the global settings.
* - Defaults to `RAB_TRINARY_VAL_NONE`
* - Bit 2 ~ 3: `r5900UseDollar`. Value of the `RabTrinaryValue` enum.
* - `RAB_TRINARY_VAL_TRUE` forces the use of dollar signs ($) on R5900's VU instructions
* - `RAB_TRINARY_VAL_FALSE` forces disassembling to not use of dollar signs ($) on R5900's VU instructions
* - `RAB_TRINARY_VAL_NONE` leaves this decision to the global settings.
* - Defaults to `RAB_TRINARY_VAL_NONE`
* - Bit 4 ~ 5: Reserved for future use.
* - Bit 6 ~ 7: Reserved for future use.
* - Bit 8 ~ 9: Reserved for future use.
* - Bit 10 ~ 11: Reserved for future use.
* - Bit 12 ~ 13: Reserved for future use.
* - Bit 14 ~ 15: Reserved for future use.
* - Bit 16 ~ 17: Reserved for future use.
* - Bit 18 ~ 19: Reserved for future use.
* - Bit 20 ~ 21: Reserved for future use.
* - Bit 22 ~ 23: Reserved for future use.
* - Bit 24 ~ 25: Reserved for future use.
* - Bit 26 ~ 27: Reserved for future use.
* - Bit 28 ~ 29: Reserved for future use.
* - Bit 30 ~ 31: Reserved for future use.
