[NFC][AArch64]Precommit test cases to show ORR is better when one operand is a shift of the other operand

In `bfi-not-orr` tests, bfi/bfxil are better since they simplifies away two instructions (extracting bits into destination directly)

In `orr-not-bfi` tests, orr is better since both orr and bfm would simplify away one instruction (the shl node), orr has higher throughput and shorter latency than bfm.
