  -----------
  [Thumb2][ARMAsmParser] Fix processing of `t2{LDR,STR}{*}_{PRE,POST}_imm` when changing to its concrete form (#116757)

`t2{LDR,STR}{*}_{PRE,POST}_imm` is pseudo instruction and is expected to
be `t2{LDR,STR}{*}_{PRE,POST}`. During building the new MCInst of
`t2{LDR,STR}{*}_{PRE,POST}`, the order of operands looks incorrect.

Fixes https://github.com/llvm/llvm-project/issues/97020.
