[PATCH] D135102: [AArch64] Combine or(and(val,shifted-mask), op) to or(shl(and(srl(val,N), mask), N), op)

Actually the current implementation causes indefinite loop for 'test_nouseful_strb' in 'llvm/test/CodeGen/AArch64/bitfield-insert.ll' (check-llvm hangs at 99%). Will make fixes for that. Sorry about it.
