[PATCH 1/1] target/loongarch: LL.{W/D} need writes val to dest register after sign extension

[Song Gao]

The Manual 2.2.7.2:
    'The LL.{W/D} instruction retrieves a word/double-word data from
    the specified address of the memory and writes it to the general
    register rd after sign extension.'
