382ad6f2 - [GISel][AArch64] Added more efficient lowering of Bitreverse (#139233)

[GISel][AArch64] Added more efficient lowering of Bitreverse (#139233) GlobalISel was previously inefficient in handling bitreverses of vector types. This deals with i16, i32, i64 vector types and converts them into i8 bitreverses and rev instructions.
