B-HowellandClaude Opus 5.5 b8636b11f7 test(relinker): report the case and flag values when a masked store stub changes the flags
masked_store_lowering failed twice under Rosetta on GitHub's macOS x86_64
runner (runs 40216485859 and 40438653738) with only "Masked store stub
changed the flags", while the stored bytes, faults, vector and general
registers, red zone and RSP all matched. The message now names the form,
width, addressing mode, offset, mask pattern, fault count and the flags
before and after, so the next occurrence shows which flags change and
whether the probe faulted.
