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.
