13bbcdec - IR: Implement Instruction::mayReadOrWriteMemory with a single switch (#239479)

IR: Implement Instruction::mayReadOrWriteMemory with a single switch (#239479) Separately calling mayReadFromMemory and mayWriteToMemory performed 2 calls and was slower. This speeds up attributor-light pass up to 2.7% (callgrind), and 0.2-5.8% faster with other pending Attributor compile-time changes applied. Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
