> On aarch64, the Lowered type of struct \{bool, int128} is form \{ {i8}, \{i128} }. No padding add. This is different with x86-64, which is \{ {i8}, \{15*i8}, \{i128} } with padding add automatically.
> And here also add some type conversion between x86 and aarch64 data types.
> And also add some aarch64 cpu's feature.
