ARM64: Unable to decode `fmlalb`, `fmlalt`, `fmlallbb`, `fmlallbt`, `fmlalltb`, `fmlalltt` instructions

[TIHan]

The following instructions are not able to be decoded with cstool:

• FMLALB <Zda>.H, <Zn>.B, <Zm>.B[<imm>]
• FMLALT <Zda>.H, <Zn>.B, <Zm>.B[<imm>]
• FMLALLBB <Zda>.S, <Zn>.B, <Zm>.B[<imm>]
• FMLALLBT <Zda>.S, <Zn>.B, <Zm>.B[<imm>]
• FMLALLTB <Zda>.S, <Zn>.B, <Zm>.B[<imm>]
• FMLALLTT <Zda>.S, <Zn>.B, <Zm>.B[<imm>]

The decoder just fails and stops.

Those ones seem to be added with LLVM-18. At least this is the version I can find the first regression tests in LLVM for. We will update it after the #2231 is done. Which should be this month, if anything goes by plan.

Thanks for the update!
