This patch adds `llvm.indirect_br`.
LLVM Language reference suggests that repetition of labels, although allowed, is not useful. The same behaviour is implemented here. Also, the order of labels does not matter.

Syntax:
`llvm.indirect_br <address> : <type> [ label1 label2 ... ]`

Example:
LLVM IR
`indirectbr i8* %address, [label %bb1, label %bb2, label %bb2]`
MLIR LLVM Dialect
`llvm.indirect_br %arg0 : !llvm<"i8*"> [^bb1, ^bb2]`
