IMPALA-9645 Port LLVM codegen to adapt aarch64 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.
